Since KDevelop comes with a set of built-in color themes that are dissatisfactory to my taste, I decided to copy the code highlighting and style configuration from Code::Blocks and compile a theme file that could be imported into the KDevelop IDE.
This code highlighting theme is compatible with the C and also the C++ programming language. Below is a screenshot depicting how the theme makes C code appear in the KDevelop IDE.
The codeblocks.theme file itself is here.
