Configurable semantic colors
Add a page under _Color Themes -> Highlighting Text Styles -> KDevelop/Semantic Colors_ that allows the configuration of the semantic highlight colors. Additionally, add a "global color source" setting to the language settings. When the latter is set to "From Editor Theme" we will use the colors from the theme as-is without any further blending. _Bold font for declarations_ will still make the declarations bold in addition to the bold settings from the config dialog. Local rainbox colorization is not affected by this at all. See also: https://invent.kde.org/kdevelop/kdevelop/uploads/500467bc355906d363e3a76a9044e138/ColorConfig.png BUG: 395856
