i am trying to minimize the colors but i dont know how i can get this to work, can someone please help me out, thanks alot!

Desaturate the image, and then modify the Levels, or you can alternatively jack up the constrast of the image. Then just replace large areas of color, such as white, with a solid color. The poster kept certain areas that held a lot of detail, like face and hands. Do the same.

thank you very much, see how easy that was and how dumb i feel, i really appreciate your help man!
