Is a Lilac and Tan mouse rare to find in a pet shop? - tiniest pet shop

I have a lavender and tan (Purple back, belly so rich) female mice and a group of blue and white markings. Just had a litter of two little ones. I'm reading too much into the color and spirit, and purple / seems to be a very rare color. I was very lucky? I want to ask a forum for mice, but is not good.
