It’s converting them between color spaces. I believe that the values you send to -addColorParameter: are in sRGB because that’s the color space that the user interface operates in. But your filter will process them in either linear or gamma-corrected RGB (depending on your -properties) with Rec. 709 primaries rather than sRGB primaries.
But if I say I work in rec709 shouldn't it assume my default colors are
also in rec709 and not convert them for me? It seems wrong to munge my
default colors and give me different ones.
Can you give me an implementation of the reverse of your function so I
can pre-reverse-munge my defaults (when I define the parameter) so I get
back what I gave you initially?
