i totally agree with you on the Biaks!! that is what i have and if things go like they are going, mine should turn into a tri color. he/she (i need to invest in some probes) is a weird shade of green, not your typical green with lots of yellow still. its a yearling so hopefully it will throw some blues and keep the yellow.
i love the darker animals like yours! also you gotta love the masks that biaks tend to have!!!
