This Plain coloring game lets you pick a picture and color it. I found the controls can feel clunky when moving the cursor to pick a shade.
Step, click on the color palette, select a brush, and start filling in the pictures.
The controls are clicking on colors and tools. There are no rules, no scores, no timer, no hints, no toggles, no modes, no levels, and no difficulty.
Most players find it better to click the color first, then select the brush to start. There is no pressure to finish anything.
