I fell a bit behind with this, though we upgraded the forum. But thought to reply to the people who took the time (many thanks!) to look into this thread.
Thanks. If I click on your link, Wave finds 13 accessibility (low contrast) issues, but not on the colours themselves. That’s because, unlike the colours page, it does not show how they are used (as background or foreground with lettering).
Let me know how I can help; it does have many contrast errors.
