We have three polygons $($A$,$ B$,$ and C$)$ in front of each other. The background A is Red, the color of the front polygon C is $(0\mathrm{.}4,0\mathrm{.}6,0\mathrm{.}5,0\mathrm{.}45)$ and the color of the middle polygon B is $(0\mathrm{.}1,0\mathrm{.}2,0\mathrm{.}3,0\mathrm{.}6).$ What is the resulting color?
