So i'm trying to implement XEP 0392 using the C hsluv bindings, but I'm getting different values when I try the test data. not sure how to proceed here.. The hue's are right, but the rgb coming from the library disagrees with test data in the xep

grim, IIRC you could change the brightness and saturation before converting to RGB, maybe check you’re using the same ones as the spec?

hah yeah that's the problem.. should the lightness be at 100 for this?

I’m surprised the test vectors don’t include this information, once you figure it out I’ll submit a fix to the spec I guess.

yeah it's not 100..

maybe 50 50 ?

saturation 100, lightness 50

Ta.

Link Mauve: thanks for the obvious answer, I'm way over tired and am not thinking clear enough, but yeah it all working now :)

Great!
