Green is my favorite color. Has been for over 12 years and my wardrobe proves it.
I don't go to chat all that much as I often leave to do other things, but when I do I now use lime green italicized.
I originally was using the deeper green the jmdt uses but then people got on my case for using it so I had to change. People have been getting on me recently about the lime green but what can you do.
While the rainbow is represented, it is a pastel rainbow that doesnt have varied brightness/shading so the colors close to each other look very similar. That said, if it was opened to any color we would have one ugly looking chat room as people would pick ultra bright neon orange pink and green or other annoying colors that don't fit the scheme. With the color of the chat room background, we are kind of stuck with pastels...
