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.
