Frequently Asked Questions

Is Marker Muse free?

Yes — Marker Muse is free to explore with no account required. A free account lets you save up to 3 palettes for later, create 1 palette per month (wizard moods and custom palettes count toward this), track up to 200 markers from 1 brand, run 1 Photo Match per month, and roll 1 coloring challenge a month (the challenge of the week is always free for everyone). Marking palettes as used is always unlimited, even on the free plan. Pro membership removes all caps and unlocks all premium tools. A 15-day free trial is available — no credit card required.

What marker brands are supported?

Marker Muse currently includes color data for the following brands:

Alcohol markers: Ohuhu, Copic, Caliart, Shuttle Art, Spectrum Noir, DecoTime, Arrtx OROS, Chen Rui, Bianyo, SFAIH.

Acrylic markers: Posca, Ohuhu Acrylic, Arrtx Acrylic, Molotow, Shuttle Art Acrylic.

Gel pens: Sakura Gelly Roll, Soucolor, Languo.

Colored pencils: Prismacolor, Polychromos, Kalour.

New brands and colors are added regularly.

How does palette generation work?

Palettes are built from real marker data, color theory principles, undertones, complementary pairings, and curated color systems. Each palette is grounded in actual marker information — organized by mood and emotional theme — so the results are practical, usable combinations you can build with markers you actually own.

Which brands do generated palettes use?

By default, every generated palette draws from the full cross-brand catalog — alcohol markers, acrylic markers, gel pens, and colored pencils across every supported brand — so each palette picks the best color for the job wherever it lives.

You can change this any time with the Palette brands control at the top of the Moods tab. Choose all brands (the default), only the brands you own, or hand-pick a specific set. Your choice is remembered across sessions.

How do I limit palettes to brands I own?

Open the Palette brands control at the top of the Moods tab and choose "Only brands I own". Once you've added markers to your collection, every generated palette will pull only from the brands you actually have.

Prefer a particular mix? Tap "Pick specific brands" instead and select any combination — palettes will draw only from those. Your selection sticks until you change it.

What is the Palette of the Week?

Every week, a new featured palette greets you at the top of the Home tab — a hand-picked mood to spark your color sense and point you toward combinations you might never have reached for on your own.

Tap "Use This Palette" to open it, see how to use each color, and start coloring. You can also flip on "My colors only" to rework that week's palette around the colors you already own — one free rebuild for everyone, unlimited with Pro.

It's a fresh little moment of discovery to come back to — a new palette to fall for, every week.

What are Coloring Challenges?

Coloring Challenges are playful, on-demand prompts for your next coloring session — color rules like "warm colors only", technique dares like blending with just three markers, moods, seasonal themes, retro aesthetics, composition constraints, and pure random chaos (including a wildcard marker pulled from your own collection).

Tap "Dare Me To Color" on the Home tab, pick the categories you're in the mood for, and hit Generate. Each challenge comes with a difficulty, a rough time estimate, a helpful tip, the skills it stretches, and — where it makes sense — an example palette built from real markers in the database.

There are no deadlines, schedules, or streaks — challenges only appear when you ask for one. Save the ones you like for later, mark them done when you finish, and share your result to the community so others can see your take on the same challenge.

Everyone gets the free challenge of the week — a new one every week, no account needed. Free accounts get 1 custom challenge per month; Pro members generate without limits. Guests must sign in to generate a custom challenge (the weekly challenge is always free for everyone).

How does Marker Muse handle my artwork and swatch photos?

Marker Muse does not use generative AI to generate, recreate, or alter your artwork. Photo Match and custom-supply swatch sampling process the colors you select on your device.

Swatch tools sample color from the area you choose; they do not infer marker or supply names, codes, or identities. You enter those details yourself.

When you choose an upload feature such as sharing community artwork, setting an avatar, or saving a book cover, that image follows the feature's existing upload flow so it can be shown or saved for that feature.

What makes Marker Muse different from other coloring tools?

Most coloring tools are built around a single brand. Marker Muse is built around color itself — a cross-brand database covering alcohol markers, acrylic markers, gel pens, and colored pencils from over a dozen brands.

Because Marker Muse tracks color data across brands, you can compare a Copic marker to its closest Ohuhu equivalent, find a Posca shade that matches a colored pencil you already own, or identify which brands overlap so you don't accidentally buy duplicates.

Palettes and color recommendations are built from real marker data — not AI suggestions — so the results are consistent, repeatable, and grounded in colors you can actually buy.

What is the Color Lab?

The Color Lab lets you build a custom palette from up to 8 colors. Add any markers you own or want to explore, and see how they work together as a group. It's a sandbox for testing combinations before you buy.

What is the Mood Wizard?

The Mood Wizard is a guided palette discovery tool that helps you find color combinations based on feeling rather than formula.

You start by choosing a subject (like a forest, a cityscape, or a cozy interior), then a tone (moody, soft, dramatic, earthy), and the app generates a palette that fits that emotional direction.

From there, you can fine-tune the result with four mood sliders — Soft to Dramatic, Muted to Vibrant, Cold to Warm, and Natural to Surreal — shifting the palette until it feels exactly right.

How do I know which color to use where?

Every palette shows you how to use each color — which ones are your highlights, shadow tones, base colors, and accents — so you can see how each one works in a finished piece.

Instead of staring at swatches and guessing, every color gets a job: this one is your deep shadow, this one is your warm base, this one pops as an accent.

It helps you visualize how a group of colors actually work together before you pick up a single marker.

What is Gap Fill?

Gap Fill looks at a palette alongside the markers you already own — across every supported brand — and suggests specific colors that would complete or extend it.

It checks your own collection first, so the colors it points you to are ones you can reach for right away. If a palette calls for a warm mid-tone and you don't own anything close, Gap Fill points to the exact markers — across any brand — that would fill that gap.

It's designed to help you build richer palettes from what you have, and shop smarter when you don't.

What is Color Bridge?

Color Bridge lets you match a color across different brands or media types.

For example, if you love an Ohuhu marker but want to find the closest Copic equivalent, Color Bridge finds the nearest match based on actual color data — not just similar names.

It works across alcohol markers, acrylic markers, gel pens, and colored pencils, so you can translate colors between any two brands in the database.

How accurate are the marker color swatches?

Every marker in the database has community-voted accuracy ratings showing how closely the displayed hex value matches what the physical marker looks like on paper. You can see the vote breakdown on any individual marker page.

Can I share my finished coloring pages?

Yes. The Community tab is a gallery where colorists share photos of finished pages alongside the palette they used — so you can see how a palette actually looks once it's colored in, not just as swatches.

When you find a palette you love, you can post your own coloring to it: add a photo, and Marker Muse turns it into a shareable card showing the palette's colors and marker codes, ready to save or post anywhere.

It's a relaxed, inspiring way to discover new combinations and see real work from other marker artists.

How do I report a community photo?

Every community photo that isn't your own has a small flag icon next to the like button — tap it, pick a reason (inappropriate, spam, not coloring-related, or something else), and you're done.

Reporting a photo hides it from your feed right away. If enough people report the same photo, it's hidden from everyone automatically while our team takes a look. We review reports and remove anything that breaks the rules.

Can I find my specific Ohuhu marker set?

Yes. Marker Muse maps Ohuhu's real set lines, so you can pull up the exact box you own and see every marker in it.

The two big core ranges are the Oahu line (from Oahu 40 all the way up to Oahu 320) and the Honolulu line (Honolulu 24 through Honolulu 320), plus the smaller Kaala sets like Kaala 24 Basic and Kaala 60 Landscape.

You'll also find the specialty boxes — skin-tone, grey-tone, and pastel sets — and the Michaels store-exclusive Oahu sets (24, 48, and 128).

Each set page shows every marker in the set with its color, code, and accuracy data.

What's the difference between Ohuhu codes and legacy codes?

Ohuhu repackaged their marker line in 2023, renaming all the codes (e.g. B01 became BG04). Marker Muse maps both old and new codes together so you can search by either — useful if you have older markers or older reference charts.

What devices does Marker Muse work on?

Marker Muse works in any modern web browser on phone, tablet, or desktop. It's designed mobile-first but works great on all screen sizes — no app download required.

How do I save palettes and collections?

Create a free account to save individual colors, build collections, and access your saved palettes across devices. Sign-up takes under 30 seconds with Google or email.

How do I tell Marker Muse which markers I own?

The fastest way is to add the sets you own. In My Stuff, tap a common Ohuhu set to add it in one go, or open the full set picker to find the exact box you have — every marker in it is marked owned at once.

You can also mark any single marker owned right where you see it: tap the small dot on a marker in a palette or on its detail page. Tap again to unmark it.

Once you've marked what you own, palettes can pull from just your markers, and Gap Fill can show you exactly what's missing. Sign in and your owned markers sync across every device automatically.

What's the difference between saving a palette for later and marking it as used?

Every palette has two independent actions. Tap the bookmark (🔖) to save a palette for later — a wishlist of combinations you want to try. Tap the check (✓) to mark a palette as used — your record of the palettes you've actually colored with.

The two are separate, so a palette can be both saved for later and marked as used at the same time. Both show up in My Stuff under your saved palettes.

On the free plan you can save up to 3 palettes for later, while marking palettes as used is unlimited — keep a full history of everything you've colored, even without Pro. Pro removes the save-for-later limit too.
