Color adjustment for printable artwork

In the Online Version, you can adjust the color of cap images so the finished mosaic resembles your original photograph more closely — exactly what you want from a digital design or a printed poster.

What color adjustment is for

Real cap photos rarely match your source image perfectly. Color adjustment closes that gap for digital results: tune cap image colors — including brightness, saturation, and contrast — until the mosaic reads like the original photo.

This is the right tool when the destination is a screen or a poster: the printed cap in the artwork does not need to match a physical object on a board.

Disabled in physical mosaic mode — on purpose

In the Standalone Version's physical mosaic mode, color adjustment is disabled. When you are going to assemble the mosaic from real caps, the preview must show the caps as they actually are. A recolored preview would mislead every placement decision you make during assembly.
