Unknown Coturnix color pattern.

Hello I was wondering if anyone knows what pattern this is. The pattern is only on the breast and is present on both a male and female pharaoh and Italian quail. I haven't seen this before and was wondering if anyone could enlighten me on the name of said pattern

no idea but it's beautiful! The back looks like a standard wild type brown, but I have no idea about the breast feathering
