Think pink

[Ksenia]

Hello!
Today I saw one T-shirt. And there were such words: THINK PINK. Below there also were words about some National Park.
Does this expression mean something? Or it's just a combination of words?
Thank you!

Pink ribbons are used for awareness about breast cancer. Could there have been some connection?

Thank you so much! I believe that there can be some connection. Because there were some wors about health and so on.
