Practical Color Theory for People Who Code (2016)
This site assumes that for a designer complementary colors are defined as pairwise opposites on the RGB wheel. This is a common mistake.<p>Complementary colors have two properties:<p>1: Mixed together physically or optically, they produce a neutral. For this the RGB pair sets are the most truthful.<p>2. Incorporated into the same design, they present as &#x27;perceptually opposite&#x27;. For this the RYB pair sets are the most truthful.<p>1. Is easy to prove (Muncell for physical mixing or Maxwell for optical mixing). 2 is not yet proven, but my own work certainly supports it (*informal tests on large groups of art students).<p>The genealogy of RYB complementary colors goes back to before Leonardo DaVinci&#x27;s, who defined these pair sets as retto contrario (literally ‘exactly opposite’).<p><a href="http:&#x2F;&#x2F;www.treatiseonpainting.org&#x2F;cocoon&#x2F;leonardo&#x2F;chap_one&#x2F;vo1&#x2F;CID71" rel="nofollow">http:&#x2F;&#x2F;www.treatiseonpainting.org&#x2F;cocoon&#x2F;leonardo&#x2F;chap_one&#x2F;v...</a>
