goog.color Namespace.HslHSL color representation. An array containing three elements [h, s, l]: h (hue) must be an integer in [0, 360], cyclic. s (saturation) must be a number in [0, 1]. l (lightness) must be a number in [0, 1].
.HsvHSV color representation. An array containing three elements [h, s, v]: h (hue) must be an integer in [0, 360], cyclic. s (saturation) must be a number in [0, 1]. v (value/brightness) must be an integer in [0, 255].

.hslDistance(hsl1, hsl2)Calculates the Euclidean distance between two color vectors on an HSL sphere. A demo of the sphere can be found at: http://en.wikipedia.org/wiki/HSL_color_space In short, a vector for color (H, S, L) in this system can be expressed as (S*L'*cos(2*PI*H), S*L'*sin(2*PI*H), L), where L' = abs(L - 0.5), and we simply calculate the 1-2 distance using these coordinates
