Her red is the matte red used on "Baby Stockings," the Rice Krispies baby. Her green is supposed to be the same as Gusty's, but I don't have one to compare. Their Dollyhair color names are Candy Apple and Sea Nymph, but there's a number of reasons not to buy from there.
As for length, the mane on mine is about 6 1/2 inches, while her tail is about seven.
I hope that helps!
