Why do people make pages highlighting colorizing things, and then make the subtitle of the page (and other text) be blue on black? This does not inspire confidence.
Purple and orange and green and white on dark blue. My eyes hurt reading this.
Pick a couple of colors with relatively high contrast, and make sure the text isn't lighter than the background.
I ported a theme called Tricolre across which is much more subdued, the pull request[1] just got accepted a few minutes ago. Hopefully I can get a few more themes done, they're very simple to create. The joy of open source is that if there's something you don't like about someone's code, you can just fork it and make whatever changes you want.
