A great site for colors and genetics is http://www.rabbitcolors.info/int/en/index.html . Hundreds of photos of rabbits(I'd guess almost every breed is represented somewhere), arranged by color, extension, type, fur, etc. A bit intimidating at first, but worth the time to get used to it.

Also, Roy Robinson's book on Genetics in Rabbits in online at the site. It's a very thorough book, from 1958. goes into a lot of detail. You need a specific plug-in to download the book, but it's available right there on the page. Well worth a look if you're interested in genetics. http://lit.rabbitcolors.info/

Feel free to add other links you've found that help explain genetics or the colors.

That is one of my favorite links!

www.amysrabbitranch.com has lots of pictures and lots of information

That was a great web site for colors
