I sympathize - I'm trying to save a bit of money and so coloured my hair myself yesterday. The box said "chestnut" and looked a nice normal brown (like I always have, it's my natural colour, I just dye to cover the grey). Chestnut my backside, I now have hair one shade lighter than black, not good with my pale skin, ugh.
At least you have Tiffany to look forward to!
