I have never quite figured out how the schema dialogue under setting/configure konsole for konsole 3.5. Once, almost by accident, I obtained a gorgeous random color effect that was so beautiful I used a collage of screenshots as a backdrop for my twitter page. I haven't been able to recreate the effect since. I'd like to use colored screenshots to dress up a tutorial. Can anybody help me?

Of course, I see the "random hue" button, but getting it to work is not working.
