I raised Ruby eyed White Holland Lops many years ago. People either love ruby eye Hollands or they hate them, seems to be no middle ground. To me, they are pretty and a color you seldom see on the show table. Some people are put off by the ruby eyes but it doesn't bother me. When I raised Blue eyed Whites, everybody loved them. I admit, keeping them clean can be a challenge, especially the boys.
Until I breed her I won't know if she is a true white or a false white. A false white is a white rabbit with one broken color parent. They can "mask" their coat and genetic makeup. Think of it as they may be a broken white. When you breed a false white to a solid, you will get brokens. When I raised the REW's before, the two REW bucks I had were actually false whites, so their babies were brokens. I wouldn't breed a false white to another broken.
Using a REW can help clean up some colors and keep them from getting too dark. Breeders use them to keep their Sablepoints and Siamese Sables from getting too dark.
Elsa actually has some Siamese Sable, Sablpoint and Smoke Pearl in the background so we will see what happens.
One misconception is that using a REW will create or increase the problem of scattered white hairs or an unwelcome white spot or white toenails. This simply is not true, the REW gene doesn't work that way. People can breed black to black to black for many generations and still get scattered white hairs or a white spot.
