For Ohuhu marker artists

Know every color you own.

ColorShelf turns your marker sets into a live color inventory, gives every marker a spot in your storage grid, and builds palettes from color theory — so you draw instead of digging.

R1C2Organization

Every marker gets an address.

Describe your storage as a grid, pick an ordering like chromatic harmony, and every marker gets a unique RxCy address you can look up in seconds.

R1C3Use

Palettes from color theory, limited to markers you own.

Pick a base color and a harmony — complementary, analogous, triadic — and get palettes drawn from markers you actually own, not a generic wheel.
