Ah man, sorry to hear that. Onward and upward though.
There are a lot of different breeders for color. Sweet Seeds has a "red family" that all color up real nice, posted a link below. The plus is, they actually support our forum with giveaways and such. Pyramid has a Purple Auto that is sativa dom that is a real good smoke. I have grown it many times. Many of the Dragon line has color in them as well but it will be a few months before those become available again. That is our(the forum's) founder's seed line. I would highly recommend those when they become available.
As for the places to get seeds, there are a lot of seed banks in the UK that will ship to the States. Alibongo is one of my favorites, as is Herbies Head Shop, Attitude Seed Bank as well. Those are probably the three biggest. Attitude began having problems with credit card processing a few weeks ago so you may want to stick with the others for the time being. All ship discreetly and while some people have mentioned problems getting seeds, I have made many many orders and never had one problem with any of the three mentioned above.
