Converts the gamma space RGB color to a CIE LAB color space value! Conversion back and forth from LAB space could be somewhat lossy.
|RETURNS: Vec3||An LAB vector where x=L, y=A, z=B.|
// Desaturating a color can be done quite nicely with the HSV // functions Color red = new Color(1,0,0,1); Vec3 colorHSV = red.ToHSV(); colorHSV.y *= 0.5f; // Drop saturation by half Color desaturatedRed = Color.HSV(colorHSV, red.a); // LAB color space is excellent for modifying perceived // brightness, or 'Lightness' of a color. Color green = new Color(0,1,0,1); Vec3 colorLAB = green.ToLAB(); colorLAB.x *= 0.5f; // Drop lightness by half Color darkGreen = Color.LAB(colorLAB, green.a);
