Please give us a description of what happened.

A colourblind user was confused by the Yoast SEO Post Overview scores. He/She can't easily distinguish between good ratings, improvement, and bad ratings as he/she is not able to see the colours.

Please describe what you expected to happen and why.

We expected the overview to be categorized like the analysis in the Yoast SEO meta box. See screenshot below:

How can we reproduce this behaviour?
