PSYC 4165 Homework 5: Color Vision Part 1: x 1 = 0.45 / (0.45 + 1.05 + 0.5) = 0.225 y 1 = 1.05 / (0.45 + 1.05 + 0.5) = 0.525 z 1 = 0.5 / (0.45 + 1.05 + 0.5) = 0.25 x 2 = 1.35 / (1.35 + 3.15 + 1.5) = 0.225 y 2 = 3.15 / (1.35 + 3.15 + 1.5) = 0.525 z 2 = 1.5 / (1.35 + 3.15 + 1.5) = 0.25 x 3 = 3.2 / (3.2 + 1.85 + 0.95) = 0.533 y 3 = 1.85 / (3.2 + 1.85 + 0.95) = 0.308 z 3 = 0.95 / (3.2 + 1.85 + 0.95) = 0.158 Color 1 is the same as color 2, and they will match in hue but not brightness. Color 3 is different from both 1 and 2. C 4 = C 1 + C 2 = (1.35 + 3.2) X + (3.15 + 1.85 ) Y + (1.5 + 1.95) Z X = 4.55, x = 4.55 / (4.55 + 5 + 3.45) = 0.35 Y = 5, y = 5 / (4.55 + 5 + 3.45) = 0.385 Z = 3.45, z = 3.45 / (4.55 + 5 + 3.45) = 0.265 Part 2: RG 5 = 1.89 * 22 - 2.79 * 8.8 + 0.45 * 2.2 = 18.018
