Do you know if the doe had a tort or fawn parent? If so, she would have an 'e' hiding behind her 'ej' to make harlequins? I don't have the gene in my herd, so it's just book learning for me, but I'm pretty sure the 'ej' (also known as the 'Japanese' gene for some reason) is where the harli comes in. It's on the 'E' gene and is recessive to everything except the 'e' which - if you have two of them - makes torts and fawns. Fawns if the first color gene is an 'A' and torts if the first two color genes are 'aa'.
I'm guessing you'll get more harlies from that pair, although there's folks out there who know a whole lot more about the harli gene than me. Here's an interesting website which covers a whole pile of different rabbit color genes:
http://yellowbrookrabbitry.com/complete-rabbit-colour-genetics-guide/ They also mention a lot of the less common 'defects' such as snowballing and those random white hairs. Although, not all defects are a defect, a lot of it depends on which breed of rabbit you're working with. The buns here, English angoras, don't have as many allowable (for show rabbits) colors as some breeds do.
