Tricolor in combination with burmese

Burmese tricolor are dark brown with black and white, it doesn't give a very big contrast, but it still is appealing to the eye. I have had burmese tricolor in my lines for a very long time, they just popped up every now and then. Currently my tricolor lines are a bit more "clean" and I get less suprises as before, but I do try to keep the other colors that popped up. So I am also trying to build a line for burmese tricolor, I am looking forward to see larger ammounts of burmese with better markings.
