Color Matrix in Affinity Photo 2

[chafouin]

Hi!
Is there a way to do a Color Matrix adjustment in Affinity Photo, similar to Natron or Nuke's ColorMatrix node?


I tried the Procedural texture approach but I guess I'm not using the correct math, I couldn't get it to work.
Thanks!

I actually found the correct math from Nuke's documentation.
In case it would be helpful for someone else, here is how to do it, with a XYZ  3*3 matrix:
Output R = R * Xr + G * Xg + B * Xb
Output G = R * Yr + G * Yg + B * Yb
Output B = R * Zr + G * Zg + B * Zb
