Forumlae:
Don't forget that we are in _clamped_ RGB space, so you need to take extra care when manipulating the formulae!

game = a * hud + (1-a) * bg

hudWhite = a * hud + (1-a) * 1
hudBlack = a * hud + (1-a) * 0

vegas = ((hudWhite - hudBlack)) * bg +(1-(hudWhite - hudBlack)) * 0 + hudBlack
= (1-a) * bg + a * hud
= game

aeMain = bg
aeGame = (hudWhite-hudBlack) * aeMain + (1-(hudWhite-hudBlack)) * 0 + hudBlack
= (1-a) * bg + a * hud
= game
