(a)Aviation red— y is not greater than 0.335; and z is not greater than 0.002.
(b)Aviation green— x is not greater than 0.440−0.320y; x is not greater than y−0.170; and y is not less than 0.390−0.170x.
(c)Aviation white— x is not less than 0.300 and not greater than 0.540; y is not less than x−0.040 or yc−0.010, whichever is the smaller; and y is not greater than x + 0.020 nor 0.636−0.400x; Where Ye is the y coordinate of the Planckian radiator for the value of x considered.
