As the title says, especially if one is using flux or any similar application to reduce eye strain.
Blue also makes it really hard to read tiles in general, it’s irritating wherever it appears as a background for tiles or text.
This wouldn’t be so bad in regards to text were the selected text white, but the lack of contrast makes it borderline illegible.
I can obviously change it in my personal template for colour values, but I’m not colour-blind in any way and this irritates me and others shouldn’t have to deal with it.
