Need idea's for tattoo color

I just got a new tattoo like a week ago on my side. Its just tho outline because i couldn't handle anymore at that moment. It is two lily's with a little greenery around it. Now i just have to figure out what color i want them to be. I have 4 other tattoo's already that have lily's involed somehow and 3 of the 4 are pink so i want to stay away from another pink one. I can't decide what color i want and would like opinions on this. Any input would be greatly appreciated. Thanks so much... To see the picture e-mail me at [email removed]
