Create a color scheme based on a seed RGB color value. The scheme is composed of the seed color and a number of other colors that have the same CIELAB lightness and are equally spaced in hue (direction from a neutral reference color in the color space).
This program was specifically designed for making Linux terminal color schemes, where equal contrast is desirable and the usual HSV model misses the mark.
Manual installation:
make && sudo make install
If you use Arch Linux or a derivative, you may also install via the AUR package.
