Breast Cancer Society Donations

I have a color, please Dillema please help.?
I'm getting married June 7 next year in an outdoor ceremony in a garden. I have broken all kinds forms between 2 colors. Coral or pink (as the primary colors) and yellow as the secondary color. I was initially chose the coral products, however, that was difficult to find (linen, napkins, invitations, dresses) in the coral in particular that I wanted. So I decided to change to pink (like a baby or Petal Pink) accented with yellow and maybe a color Hot Pink. Pink is easy to find, and also links to please my boyfriend and I have decided it is to give a donation to the Society Breast Cancer because my mother had breast cancer several years ago. What color is better. Not sure if it matters but most of my bridesmaids are African American and I have one that is Hispanic / Cuban. Please Please Please help me choose a color and if you have better ideas for accent colors please advice. I'm trying to stay away from cakes, but to have a vibrant primary color. Help.
I think you should do things your invitations and light pink. thus, could accent with a darker pink and finally pale yellow. If you chose the coral, I think Peach is a color that is near, and would be really nice, with any green color (which is also a color very elastic, in my opinion) Good luck with your wedding and I am sure that whatever you decide to be absolutely gorgeous!
