Note that there are many other "colour harmony tools" available as programs or online, but most of these are of extremely dubious value, being based either on the RGB hue circle, which is very uneven perceptually and does not show accurate additive (visual) complementaries except on the red-cyan, green-magenta and yellow-blue axes, or on misguided attempts to transform this hue circle to conform to the "traditional" colour wheel (e.g. Adobe ColorCC/Kuler).
