There's a sticky with some websites at the top and tons more if you search links-to-genetics-material-t3800.html If the explanation page isn't linked on there already this site also has a useful chart as well with not every color and some color names vary by breed (chestnut is castor in rex and copper in satins) but quite a few of them with generally the most common name for a set of genes http://www.thenaturetrail.com/rabbit-ge ... pes-chart/
