fix: color flags not working

[goto-dev-null]

Technically it was just the quotes around ${COLOR_OPTS[@]} that were causing the issue, but the [@] is not necessary in this case, afaik, and just makes it harder to read

Made the flag descriptions match #93

thank for the fix

Confirmed this fixes the bug (COLOR_OPTS was a 1-element array due to the inner quotes at its declaration, so "${COLOR_OPTS[@]}" only ever iterated once over the glued string). This fix works around it via word-splitting on the unquoted expansion — merging as-is.

Nit for later: the more root-cause fix would be at the declaration, COLOR_OPTS=(${COLOR_AUTO} ${COLOR_NEVER} ${COLOR_ALWAYS}) (no inner quotes), which builds a real 3-element array and lets the original "${COLOR_OPTS[@]}" loop work correctly/robustly. Not blocking — will follow up separately.
