• Automatic color extension

  Enter the number of results to be expanded, that is, the number of expanded color systems. The algorithm calculates the uniform sampling method according to the color space, and gives the results that meet the requirements of the number of expanded colors. Simply put, the number of color systems is how many, and a few pictures are output.

  For example, 【Before processing】【color_count=1】【color_count=4】. The result is as follows:

  

• Color palette extension

  Input a set of color lists (color swatches), and the algorithm uses the swatches as the main color to expand the original image. This mode provides greater color control. The length of the color list must not exceed the specified value.

  For example, 【color_template="#DB0D0D,#0E0CBB,#FF0000"】. The color extension result is as follows:
