hexToRgb(hexString)

param color: vec3

rgbToHex(color)

colors: array of colors given as RGB triples

u: parameter at which u is to be interpolated

colorscale(colors, u, umin, umax)

function rgb_vector_to_color_string(vec3)

param value: rangin from 0 to 1

param cmin, cmax: rgb triple in [0, 1]

perform linear interpolation between two colors with value as lerp parameter

mapColor(value, cmin, cmax)

function hsv_to_color_string(h, s, v)

param value: in [0, 1]

param huemin/huemax: hue for min/max value

valueconst: hsv value for both min/max hue colors

interpolate between these two colors by blending to white in the middle

mapColor(value, huemin, huemax, valueconst)

return hue, sat, val of color in hsv model, set s to 0.8 and v to 0.9

mapColor(u, maxhue)
