🤖 Smart Image Analysis
Unlike other coloring sites where difficulty is set manually, we use an automated image analysis system that scans each illustration to measure its actual complexity. Our algorithm evaluates:
- •Ink Density — how much of the page is covered by lines
- •Edge Detail — the level of fine detail in the artwork
- •Line Complexity — the number of intersecting lines and small areas to color
Based on these metrics, each page receives a complexity score (Easy Medium Hard) that determines its difficulty level and recommended age range. Simple outlines are rated for toddlers; intricate mandalas and detailed art are rated for teens and adults.
