Canny Redux Line Art Coloring Workflow

Precise Edge Control:

The Canny algorithm, through a dual-threshold mechanism (low threshold filters weak edges, high threshold preserves strong edges), can extract structurally clear line art. This feature ensures that the generated result strictly adheres to the composition of the original line art, avoiding color overflow or contour distortion, making it especially suitable for illustration coloring scenarios that require accurate shape retention.

Free Style Transformation:

Redux supports generating multi-style variations (such as cel-shading in Japanese manga, thick oil painting) for the same line art. By adjusting the weight of the prompt words, you can switch color styles without replacing the base model.
