I think the joke is that red has a longer wavelength than cyan (nanometers of difference). Not anything to do with colour theory. [[Special:Contributions/162.158.133.96|162.158.133.96]] 10:06, 11 December 2015 (UTC)<br />

The mouse over text makes it fairly clear that it's a joke about opposites. If anything could be added to the explanation as it stands, I might clarify that red and cyan are specifically colors of light. When shone on a single area (and therefor mixed) these two colors will create white light. When these colors of light are represented on a color wheel, they are placed opposite each other. So cyan and red in this sense fit as opposites, like big and small, alkaline and acidic.</div>108.162.227.125
