What is Mobile Coloring Book?

Mobile Coloring Book is a Flood-Fill Geometry and Touch-Targeting simulator. The technical core is the "Seed-Fill Algorithm"—calculating the boundaries of a closed polyline and applying a color-value within a "Tolerance Threshold." It is optimized for UX-Response Times on high-latency touch screens.

Description

A mobile-optimized digital art studio. Features bucket-fill and free-hand drawing tools across diverse templates, emphasizing a streamlined UI for precise color selection and touch-input brush strokes.

How to Play

Select a color and tap a closed segment. The gameplay is Creative Asset Completion: fill the black-and-white wireframes. Interaction involves Zoom-Interpolation—using a "Pinch" gesture to increase the "Pixel-to-Input" ratio, allowing for the precise filling of 1-5 pixel wide details.

How to Get High Scores in Mobile Coloring Book

High scores (Gallery Rating) are based on "Chromatic Balance." The pro secret is to use the "Palette Memory" feature. By sampling colors from one side of the image and applying them symmetrically to the other, you create a "Professional Composition" that the game's "Aesthetic Algorithm" rates higher than random fills.

Frequently Asked Questions

Q: Why does the whole screen change color?

This is a "Boundary Leak." If a line in the template is not fully closed, the fill-algorithm will spill out. Use the "Pencil" tool to close the gap before filling.
