There is now an active thread over on tinkering changing 1.8 color and font schemes. There will be even less than 1% involved in that.
Activity on that thread must be capturing something though about the mood were the tip of the iceberg feels compelled to delve into configuration files and hex codes. Partial solutions there won’t even persist from patch release to patch release. But I do get it.
Some may not have noticed but Classical has been singled out for its own extremely low contrast light theme which is different to the light theme default. If you have a hybrid Pop/Classical library apart from anything you are constantly jumping between subtly different themes. I find switching the low contrast grey on grey Classical theme to the default grey on white Pop theme a marked readability improvement. Before delving into hex codes you can experiment simply by removing the “Classical” tag from a Classical album page and see if you prefer the result.
