Hm.
Let's see ... I blew my cash on dye as well. I already had all-black 15K Enchanters, but I was tired of it. And all-black 15K Enchanters is just SO cliche. Ugh. So I dyed the coat and boots with a mix of red, green and black. I discovered I HATED it.

I dyed it over with black AGAIN. It stayed that way for about a week. Then my GW computer broke down, and I was stuck on a very laggy laptop.
I couldn't do anything while on that laptop but just stand around in cities and outposts. I was bored out of my mind. So I blew more money on dye. I still wanted brown 15K Enchanters, so strip that black dye off, and use a red+green mix on it. I hated it again.

But I was still bored.
I ended up just randomly mixing dyes, including black, and experimenting with them. My mesmer finally ended up with this dye job:
While my spendthriftiness isn't as impressive as some other people's here, I'd say I burned about 50K during that fit of indecisiveness.
