ColorShelf overview

Use

Palettes from color theory, drawn from your desk.

Pick a base color and a harmony — complementary, analogous, triadic — and get a palette made only of markers you actually own. No more choosing colors on screen that don't exist on paper.

No account needed — your work stays in this browser until you sign in.

One base marker, three harmonies — every result is a marker you own.

How it works

  1. 1Pick a base color

    Start from any marker in your inventory — the color your drawing is already anchored on.

  2. 2Choose a harmony

    Complementary, analogous, triadic and more, computed from real hue relationships rather than a generic wheel.

  3. 3Save the palette

    Name it, tag it to the drawing it belongs to, and come back to it with the markers still on hand.

Color theory that respects your inventory.

Inventory-aware by design

Every suggested color maps to a marker you own. If it's in the palette, it's on your desk.

Real color relationships

Harmonies are computed from hue geometry, so complementary actually opposes and analogous actually neighbors.

Save and organize

Keep palettes per drawing, tag them, and curate the ones worth returning to.

Share on Explore

Publish palettes for other artists — and browse theirs, filtered to ones you can fully reproduce with your markers.
