Description Noel Santos 2025-08-05 00:56:36 UTC 
The color adjustment filter has a "channel" selector where the default option is "RGBA," but while this option is selected the alpha channel isn't processed by the filter. It should say "RGB" instead.

Hi Noel, thanks for your report

To be hyper-specific: this is about the "Color Adjustment curves" filter. I cannot personally attest to which is more correct (RGB vs RGBA), but it sure does seem like the alpha channel is unaffected and that RGB is a more accurate label. Should be an easy fix in that case.

Pushed by woltherav into branch 'master'.

Make the all-colors channel in the adjustment filter not contain "A".

We don't seem to have a generic function to only get the names of the color channels,
or even a way to find canonical short names for color channels, so hardcoding them
for now makes the most sense.
