What is Color & Create Lab?
Color & Create Lab is a free browser-based creative toolkit from the artist brand RawSueshii. It has two main tools:
- a color palette generator that builds mood-based palettes using markers from the Ohuhu Honolulu 320 set, showing both classic and new marker codes plus hex values, and
- an art prompt generator with a library of 365 original drawing prompts for daily inspiration and creative block.
It requires no account and no download; saved palettes are stored locally in your browser.
What is the Ohuhu 320 marker set?
The Ohuhu 320 is the 320-color Honolulu-series alcohol-based art marker set made by the marker brand Ohuhu. Ohuhu updated its labeling system, so the same ink colors exist under two naming schemes: classic codes (such as Y010 “Primrose”) found on older caps and printed charts, and new codes (such as Y00 “Lemon Mist”) on newer packaging. Only the labels changed — the colors are the same.
We publish a full classic-to-new conversion chart covering all 320 colors, and every tool on the site has a Classic/New toggle so you can work in whichever system matches your markers.
How does the Palette Generator work?
Pick one of 18 color moods (for example Lemon Drop Pop, Ocean Breeze, or Galaxy Pop) and click Generate. The tool produces a five-color palette drawn from curated, mood-tagged combinations. Each swatch shows its Ohuhu marker code and hex value, with a toggle between classic and new codes. From there you can:
- lock swatches you like and re-generate the rest,
- shuffle for a fresh combination in the same mood,
- switch to Build Your Own mode and assemble a palette from the full 320-marker catalog, and
- save palettes locally or share them by link.
It's free and runs entirely in the browser — no sign-up. Try the palette generator.
How does the Art Prompt Generator work?
The Art Prompt Generator draws from a library of 365 original art prompts — one for every day of the year — written to help artists beat creative block. Every prompt is tagged with a vibe, a difficulty level (Easy, Medium, or Advanced), an estimated time, and a season, and each one is linked to a matching Ohuhu marker palette through one of five palette moods: Dreamy & Soft, Chill & Calm, Moonlit & Wonder, Bold & Confident, and Playful & Kawaii.
There are two ways to use it: generate a mood-matched prompt alongside your palette on the homepage (the prompt follows the color mood you picked), or browse and search the full 365-prompt library with filters for vibe, difficulty, and season — and jump straight to a suggested palette for any prompt.
