imgscheme [-N color] file
imgscheme generates a terminal color scheme from an image file. It attempts to make the generated colors correspond to prominent colors in the image, and also close to the corresponding colors in a base color scheme. If file is absent, imgscheme reads from the standard input. The colors in the base scheme can be set using numeric flags corresponding to the 16 ANSI colors (0-15) as hex triplets /[0-9a-f]{6}/ The generated colors will be output in order as hex triplets.
