Saturday Morning is a light theme spun off from Quiet Light by Ian Beck. I thought it was too loud, and I didn't really like some of the uses of green and purple. Great theme though. I've taken "Saturday" from the Boards of Canada song "Hey Saturday Sun".
If there are issues with my themes, I encourage you to roll your own, especially light themes which are in short supply. I have strange opinions on how things should look given my own very specific issues with vision and I probably want things to look the way I decided. If you spot something glaring and disturbing though, feel free to reach out.
