Changing default link color mixing in minimal-mistakes

I wanted to override the default link colour for the dark theme in minimal-mistakes by pulling them out of their skin file and adding them to main.css before the import, as I have done here.

However, the colour is much darker than I expected from the mixing I specified. Interestingly, if I set it higher or to 100% for the primary colour (bright teal) it becomes even darker. Is there some additional mixing going on elsewhere? I scanned the stylesheets, but didn’t find anything…

Maybe you can open an Issue on the official repo.
