How to match colour in SKIA and STRIDE

vvvv gamma question
#1

hi all,

Here you see the pipet from my colour iobox, then stride background, then stride plane with just ambient light = 1, then skia texture within stride. (the saturated blue is my windows desktop!) All using the same colour. iobox and skia texture matches.

I already disabled “default post effects” on my scene window.
What am I doing wrong?
