Indigo font on brown/dark-grey/purple background is hardly readable. Blue is just slightly better.
It's not like I've known this to be a problem and have just done nothing about it. Different browsers have different capabilities, and if what seems like an obvious problem to you goes on for a long time without being fixed, this could be because I am not experiencing the same problem as you are.
This particular problem is probably because I am using color-mix for the link colors instead of custom properties like I am for all the other color changes, and custom properties have better support than color-mix. So there may be an occasional browser that supports custom properties without supporting color-mix. However, I have not been able to locate one. While I have some old devices with old browsers that do not even support dark mode, every browser I have found to support dark mode supports it fully with both custom properties and color-mix.
So, first, I would like you to report to me which version of which browser on which operating system or device has this problem. Then I would like you to make sure everything is up-to-date. Make sure that your device is fully updated and that your browser is the latest version. After doing this, let me know whether the problem persists.
