Consider any three valid colors c1, c2, and c3 with coordinates (x1, y1), (x2, y2), and (x3, y3) in the chromaticity diagram of Fig. 6.5. Derive the necessary general expression(s) for computing the relative percentages of c1, c2, and c3 composing a given color that is known to lie within the triangle whose vertices are at the coordinates of c1, c2, and c3.
