Don't translate ColorPicker color labels

[KoBeWi]

Prevents this

An alternate solution is to use context for these labels, something like ETR("B", "Color Channel").

Is translating "RGB" even a thing? I never seen a software that does it.

Btw, we should likely add translation context to the other ETR("B") regardless of this change. (And the other kB, MB, etc. for consistency.)

I've never seen that either. Maybe some languages do that. Just checked GIMP does i18n for R, G, and B for its colorpicker.

At least the Wikipedia page has the acronym translated and not just transcribed in some languages, so I think there's room for it, and it'd at least be transcribed in languages using Cyrillic for example

I can imagine КЗС (красный, зелёный, синий) in Russian localization, but I think that most often RGB is not translated. On the other hand, providing context will allow translators of each locale to decide whether to translate it or not.

How to add localization for labels if they are constant strings stored in a raw array? It would require some rewrite of color modes.

That could be a separate PR.

Thanks!
