Red It Is!

Our latest poll asked what color the sun faded on a carpet that was brown and turned green.  The answer is red.

Since carpets are made up of the three primary colors yellow, blue and red, and since brown is a mix of all three primaries in uneven amounts (black is all three primary colors in even amounts), the missing color would be red. Since the remaining color was green and green is a combination of yellow and blue, the only color missing is red.  When a situation like this requires color dyeing, one would need to add red dye back into the green area to return it to brown. Interestingly, red dye is the weakest dye and the first color that the sun will fade.
