Hi Josh,

There are two new SCs for contrast, one for informational graphics, the other for interactive elements.

The interactive elements one will cover “focus and select indicators”, requiring 4.5:1 unless it is a “thicker line” (>2px) in which case it is 3:1.

(NB: Ignore the text in the URL, there have been many iterations and the URLs can’t change. Also, David and I suggested some simpler wording/formatting which Glenda is going to update on that page.)

Cheers,

-Alastair
