Make Breeze Dark's Complementary color set not complementary
Despite the name, Complementary colors are used more like an always available set of dark color scheme colors. This means that in situations where you'd expect colors to always be dark, they become bright white with Breeze Dark because they were given Complementary colors rather than hardcoded dark colors. I don't think all these instances where the complementary color group is used like that will be fixed before Plasma 5.21 is released, so I'm making the Breeze Dark Complementary color set use normal Breeze Dark colors. It's not like you'd want to use light colors in a dark theme very often anyway, although it is possible, especially in text processing apps where the content area is always light.
