I don't care much about the color scheme. During my daily work, I switch between at least four editors (AtmelStudio, Notepad++, joe in a PuTTY or xterm window, Qt Creator). All of them have usable defaults, except for PuTTYs dark blue on black, which is a little bit too dark and has to be changed. All editors highlight keywords, strings, comments, and some other things, and that's good enough for me. I work with different languages (C, C++, Perl, Bash, Batches, XML, HTML, Markdown, and others), with different highlighting, and so things never look the same anyway.
