    L = R+G+B/3
    S = 1 - (1/L)*Min(R,G,B)
    H = cos^-1( (.5*(R-G) + (R-B) ) / (((R-G)^2 + (R-G)(G-B))^.5) )

    (I stole it off of some1 else's site0

    I'm sorry but thats far from correct!

    Fisrt of all theree must be a more accurate function for the L, cause in most cases it misses big time, S and H are incorrect cause theres something missing!

    Hope to hear from any of you guys who can help me out!
