Abstract
Diffusion coloring of vector graphics artwork is performed in constant time based on the number of color channels in a specified color space. In some examples, a method may include establishing color handles within an artwork, and defining mesh vertices distributed throughout the artwork. The method may also include determining a resultant color at each mesh vertex by solving the Laplacian equation for each of i color channels in a color space, wherein solving the Laplacian equation for each of the i color channels produces a corresponding i color values that collectively define the resultant color. A color for a pixel in the artwork can be determined by interpolating between the resultant colors at the mesh vertices.
