Here I will experiment with the Wikicode formatting rules.

This is the formula to calculate the relative luminosity of two colors, as required by Section 508 accessibility standards. R₁, G₁, and B₁ are the red, green, and blue color values, respectively, of the first color. R₂, G₂, and B₂ are the red, green, and blue color values of the second color. All color values are integers between 0 and 255.

${\frac {(0.2126+{\frac {R_{1}}{255}}^{2.2})}{(0.2126+{\frac {R_{2}}{255}}^{2.2})}}+{\frac {(0.7152+{\frac {G_{1}}{255}}^{2.2})}{(0.7152+{\frac {G_{2}}{255}}^{2.2})}}+{\frac {(0.0722+{\frac {B_{1}}{255}}^{2.2})}{(0.0722+{\frac {B_{2}}{255}}^{2.2})}}$
