Low contrast when browsing GitHub profiles while using the "new" Dark Default theme

Greetings, everyone.

A few minutes ago, I noticed that, (probably) after the recent colour contrast changes, the colour contrast actually feels lower when browsing user profiles. In specific:

Dark default:
Background: #0d1117
Repo names $ hyperlinks: #3f84e4 (5.07:1 contrast with the background)
Repo descriptions: #7a8490 (4.98:1 contrast with the background)

Now, comparing with the protanopia/deuteranopia/tritanopia themes, which appear to be using the old colours for these divs:
Background: #0d1117
Repo names & hyperlinks: #58a6ff (7.49:1)
Repo descriptions: #8b949e (6.15:1)

I assume it doesn't feel like a huge difference to users that have a "20/20 vision", but as someone with moderate myopia, I'd suddenly find it a bit harder to browse profiles on GitHub without using my glasses, zooming in more, or crouching towards the screen. Would it be possible to replace #3f84e4 with #58a6ff and #7a8490 with #8b949e on the Dark Default theme?

EDIT: I see this now also applies to quoted text etc. GitHub definitely will be harder to use.
EDIT #2: Sadly, I have now moved to the not-as-good-looking Dark High-Contrast theme, as the normal theme is partially unusable for me now.

Hey @bandisast,

thank you for your feedback. The issue we are having with the the previous link and muted color (e.g. used for repo descriptions) is that both don't have a 3:1 contrast ratio to the default color. However this is required by wcag 2.1 to assure users can distinguish links from text. This leaves us in a mathematically very tight spot.

The problem, as mentioned in the other thread, is that human color perception is not linear and e.g. a color on dark background needs a different (higher) contrast ratio than a color on light background. This comment from the other thread summarizes it well.

It would be nice to at least have the option to make the accent color brighter (without using the dimmed theme, which makes the background brighter and thereby lowers contrast again).

Oh no, I was hoping it was a bug of sorts. I'm using the Dark Dimmed theme and suddenly the whites are really bright and the blues have become more dark and saturated... it feels really noisy.

Thanks for posting the old colors, might have to work around it with an extension.

Hey @karmaral this is something we will be addressing.

Thank you, indeed the visual needles are gone!

I will look into this. Thanks for the report.
