Chromivell

Find a new perspective in a little ink. Chromivell is an offline puzzle studio where simple stamps become layered color compositions.

48 STUDIES IN SHAPE AND COLOR
Explore six collections of five-by-five print puzzles. Match each target within its impression allowance. Play the studies in any order, from first impressions to layered studies with paper masks.

PREVIEW YOUR NEXT IMPRESSION
Choose a stamp, tap the sheet to position it, rotate in quarter turns and inspect the outline before printing. Every impression is deliberate. Undo your last move or clear the current sheet to try a different approach.

DISCOVER HOW INKS MEET
Cyan, magenta and yellow combine into violet, green, orange and deep ink. Repeated ink does not darken a cell. The Paper stamp clears the cells it touches, so the order of your layers matters.

A RECIPE WHEN YOU NEED ONE
Each study includes a complete working recipe with stamp, ink, rotation, row and column. Follow it from a blank sheet or use it to understand an unfamiliar overlap. Collected studies remain collected when you revisit them.

MAKE YOUR OWN EDITIONS
Free studio opens every stamp shape and ink. Build a composition with up to 80 impressions, save up to 100 prints in your local gallery and reopen a copy for more experiments. Export a clean 1200 x 1200 PNG through Android's document picker.

A QUIET PERSONAL WORKSHOP
Enjoy warm paper, tactile artwork and light, dark or system appearance. Drafts save after each change. Delete individual saved prints or clear all workshop progress, drafts and saved prints in Preferences. Your appearance choice and exported files remain.

OFFLINE BY DESIGN
No accounts, ads, analytics, in-app purchases or cloud database. No app permissions are requested. Your workshop stays on your device. Export destinations and support email are handled by the external providers you choose.
