Someone else pointed to that tractor earlier in the thread, so I have seen it.
I haven't really thought going to a third color, like adding white, would work out. But I'll try it with PaintShop and see how it looks.
Here's the inspiration for the color scheme:
Bryan's 1450 recolored doesn't really capture the complete look I'm going for, as I want to run ag tires all around. Maybe I'll see if I can edit them into the pictures. I wanted to go with the industrial-type tires they run on these scuts, but it doesn't look like you can find them in a size that would run on a 1650.
