The ink is permanent.
Your first guess
doesn't have to be.
Scan a page from any coloring book, try it in the actual markers sitting in your case, and walk away knowing every code you'll need — before a single pen comes off the rack.
The real Ohuhu Honolulu 24 — every value read straight out of the app.
You own 120 markers and still can't start
Spreading out the whole case and freezing is the most common reason a page never gets colored. Too many options, no way to test one, and every stroke permanent. So the book goes back on the shelf.
HueMock takes the risk out of the decision. Try a palette on the actual page, change your mind as often as you like, and only pick up a marker once you already know it works.
Three steps, then you're coloring
No account, no import wizard, no file formats. Photograph a page and start tapping.

1
Scan the page
Photograph any page from any coloring book. HueMock straightens out the lighting and converts it to clean black-and-white line art on its own — no cropping or thresholds to fiddle with.
-
2
Fill it with markers you own
Tap an area and it floods with a genuine marker color. Not a generic palette — the real Ohuhu and Decotime inks, restricted to the sets you told HueMock are in your case. Undo goes back 50 steps, so experiment freely.

Get your codes back
Switch to View Mode, tap any area, and HueMock names the marker that made it. Take the codes to the paper page and reproduce exactly what you saw — no more "which blue was that?"
Four ways to build a palette
Every one of these works only from markers you actually own, so nothing it suggests sends you shopping — unless you want it to.
Palette Generator
Pick a base color and get a harmony built around it — analogous, complementary, triadic, split-complementary. Lock the colors you like and shuffle the rest. Or set a start and end color and let the Ombré Gradient mode find the smoothest run of markers between them.
Color Extractor
Import a photo — a sunset, a flower, a room you like — and tap anywhere on it. A magnifier follows your finger; lift it and HueMock names the closest markers in your collection, with a match-quality rating for each.
Color Converter
Paste a HEX code, type RGB or CMYK values, or drag around a color picker. HueMock returns the nearest markers you own — and can search every marker it knows, which doubles as a way to check before buying.
Set Advisor
Tells you which set to buy next by counting how many genuinely new colors each one adds to what you already own — so you don't spend £40 on a set that's 80% duplicates.
Built around your case, not the cloud
HueMock only ever suggests markers you can physically reach — and it keeps the whole thing on your device while it does.
Your actual collection
Tell HueMock which sets you own once, and every palette, match and suggestion is drawn from markers within arm's reach. 855 colors across 60 sets from Ohuhu and Decotime, with more brands being verified.
Nothing leaves your device
No account, no analytics, no ads, no servers. Pages sync between iPhone and iPad through your own private iCloud; on Android they stay on the device with manual backups.
Nothing to scan? Start with these
HueMock ships with real pages from working illustrators, free for everyone — Bear & Cat Go Spooky and Bear & Cat Go Gaming by Lala Winter, and Udderly Strange by Yellow Poppy Publishing.
They're there so you can learn the app on proper line art instead of hunting for something to photograph. If a book wins you over, HueMock points you at the printed edition — that's the whole arrangement with the artists.
