Color to alpha - changes image color/transparency

[EyeOdin]

Sadly colour to alpha in krita is not very good at all

Color to Alpha has some issues to make clean alphas

Both cases they are set to the same background color set with their picker. Performace in Krita [color_to_alpha_krita] threshold setting eats the edges of colors on the sides with high values or in low values maintains a white halo. Performance in Gimp [color_to_alpha_gimp] background is fully removed and Transparency and Opacity adjusts things without being so violent and by norm does a much cleaner removal of the color. changing values results in adjustment of colors transparency than be…

My suggestion for that operation would be to use GIMP that is way more clean handling colours. I have gimp for colour to alpha and BIMP still.
