Doesn‘t keep its promise
Claims to create balanced color palettes, then uses the highly imbalanced standard RGB color space to do so. As a result - steps between different hues are vastly different - brightness doesn‘t change monotoneously between colors - chroma doesn‘t vary monotoneously between colors I cannot even select properties besides the hue of one of the two defining colors of the palette. Finally I hate the fact that colors of a palette are not shown in a linear arrangement.
