Comment Type: technical
Summary of Issue: contrast ratio SC level
Comment (Including rationale for any proposed change):
1.4.3 Contrast (Minimum): Text (and images of text) have a contrast ratio of at least 5:1, except if the text is pure decoration. Larger-scale text or images of text can have a contrast ratio of 3:1. (Level AA)



Comment: My comments relating to this issue last year suggested the Level should be increased to A. I was advised in general terms by the working group that the issue was discussed but no specific response to my comment was provided. 



I believe this is a significant accessibility issue since in my work I have observed many people (including sizable proportion of the older population)experience difficulties in differentiating between foreground and background colours used on websites.



Proposed Change:
1.4.3 should be at Level A
