Key changes:

• Introduces check_data_for_colspace helper function to centralize data validation
• Updates error/warning messages for consistency (e.g., "three" → "3", "tetrachromatic" → "tetrachromat")

Woah! This is awesome - thanks. I’ve had a poke around locally and not found anything of note - happy to merge when you’re satisfied.

Also the copilot reviews are very cool, that’s new to me.
