When calculating relative luminance for WCAG contrast programmatically, a team member wrote a script that averages sRGB R, G, B values linearly (0.2126 * R/255 + 0.7152 * G/255 + 0.0722 * B/255) without sRGB gamma expansion. What threshold value in sRGB space determines whether a channel value is divided by 12.92 versus raised to the 2.4 power in official WCAG math?
