    I was recently browsing a beautiful red monochrome1 site. There were a few call-to-action buttons on the page that transitioned to green on hover. Where did that brown come from?! The initial red looks great, the final green looks great, but everything between is pretty dismal. Why is that? The RGB color model Red Green and Blue are the three primary additive colors.

White light is a combination of all wavelengths in the visible spectrum. Humans are trichromats, which means that we have three types of color receptors (cone cells). Our short-, mid-, and long…
