I checked out the site but didn't see where Survivors wear Fuschia. The pictures didn't say it either. Maybe I skipped over it care to link to it. Also I did noticed that the ribbon was changed to a two tone pink for Suasn Komen but her event was not the one I covered. There is also the National Breast Cancer Foundation, American Cancer Society, Breastcancer.org Non profit, Breast Cancer Coalition, just to name a few. In the last 4 years including this year I have never used fuschia. The darkest I have used is Azalea. With so many different Breast Cancer Organizations that have Run/Walk events in Atlanta I usually stick to whatever color they ask for which is usually a light or pale pink. I have done two so far this year. I did not print any for the Komen Run/Walk last year which was on May 9th but I did volunteer to help clean up after the race. From what I saw it was a sea of white and various shades of pink.
So I guess to answer the OP's question why not just ask the customer what shade of pink they would like?
