It is described in the Python _init_.py library file as, вЂњcontains darker and softer contrasting and complementary colorsвЂќ. How this algorithm operates will depend in part upon the initial hue selected.

complement returns a complementary pair.Д¬omplementary returns a list of 6 hues, or 2 groups of 3 complementary hues in a single list.

The term complementary as used above, is not identical with the rule complementary. The complementary hue is the opposite hue on the colour wheel, and the same value as hue.rotate(180). I am reminded, there is also a reference somewhere to IttensвЂ™ colour wheel, but I cannot remember where, at the time of writing, and there are frequent references to the вЂartisticвЂ™ colour wheel.Д¬omplement is the only rule to return a single addition hue. Fortunately there is a note in the tutorial page to correct this presumption. I noted the following, вЂњThe complement is the color 180 degrees across the artistic RYB color wheel.вЂќ in the Python _init_.py library file, description of вЂњcomplementaryвЂќ, which I had initially read as a typo. With the Colors library you can create schemes from the following rules:вЂќ and proceeds to list 10 rules, There appears to be 11 rules. The color library tutorial, writes: вЂњColor theory provides a visual guidance to color mixing and the visual impact of specific color combinations.
