How about - don't use colour at all, since it's just a culture-specific proxy for the actual meaning? "blacklist" and "whitelist" are challenging for ESL and for people from other cultures. Block list, allow list, filter list, etc. are all more precise terms that happen to be easier for everyone to understand.

Improving technical jargon is always worthwhile.
