@Raffriff42,
I don't know what formula's you used to calculated the HSL values but they seem to be wrong. Wikipedia contains the formula's where 0<=H<360.0, 0<=S<=1 and 0<=L<=255. I suggest you use those. Example (color_blueviolet):
R = 138 G = 043 B = 226 M = max(R,G,B) = 226 m = min(R,G,B) = 43 C = M - m = 183 B = M => H = 60*(4+(R-G)/C) = 60*(4+(138-43)/183) = 271.15 L = (M+m)/2 = 134.5 S = C/(255-|2*L-255|) = 183/(255-|2*134.5-255|) = 0.76
Also you should add an appropriate reference for this. Admin 00:18, 19 August 2014 (CEST)
