Is graypearl the same as lavender? I remember that you used to raise paints but gave them up. Is that be cause they don't breed true or do they breed true in EU?The different classic-colorations handling over the years in EU Silkies (now going for non classic-colorations)
Black Blue Splash graypearl gold Silver Red Buff Cucula Paint white
The different ways to breed them genetically are exposed here in one of my older webpages :

(is one long page, so you have to scroll dawnwords)
As the title says it are only the basic rules of color-genetics but are helpfull for every starter project-breeder.
After the basics comes in each breeder feeling for inspiration and "fingerspitzengefühl" for implementation of different genes and combinations to let act and interact in Dominant, incomplete Dominant, coo-Dominant, epistatic, recessive ….. ways to become the most beautiful "creations" in his/her personal favourite race and so resulting in ALL the different phenotypes that our chicken-colorations are rich of.
