d/23823 figure 3

u/taupelink

briefly: Y ranges from -2 to 2. Below the middle line, Y is positive and there's more green than average. In the large top and bottom areas, Y is between -1 and 1, and there is more blue than average.
u/taupelink

Note the formula for the top of the rectangle, 540+k/Y. This breaks the window up into four horizontal bands. From top to bottom, they are: -2<Y<-1, -1<Y<0, 1<Y<2, and 0<Y<1 respectively.
u/taupelink

Correction: -1<Y<0 is the top band, -2<Y<-1 the second from the top.
u/taupelink

The green component formula is k+k*Y/2. This is greater than k when Y>0.
u/taupelink

The blue formula is k+k*C(Y*1.57). This is greater than k when C(Y*1.57)>0, i.e., when -1<Y<1.
