GDScript function to convert RGB color to HSV values
Raw
rgb-to-hsv.gd
# I/O values are in the range 0.0 .. 1.0
func rgb_to_hsv(c: Color):
var M: float = rgb.max()
var m: float = rgb.min()
var v = M
var s = 0.0 if M < 0.001 else 1.0 - m / M
var h = (c.r - c.g / 2.0 - c.b / 2.0) / sqrt(c.r*c.r + c.g*c.g + c.b*c.b - c.r*c.g - c.r*c.b - c.g*c.b)
return { h=h, s=s, v=v }

It transpires that we don't need this in Godot since the Color class has properties of h, s, v. Something that I missed, but this code is maybe interesting to look at?
