How to set and get custom color

Hi,

I am working with wxWidgets and getting problem to set and get custom colour in color dialog on mac machine. Later i found that there was problem that function has not been implemented there so i try to write code with my self.

My problem is that i am able to open and select colour using NSColor but unable to set custom color in custom pallets , i have a array of color of 16 and want to set them one by one on the basis of index then how can i do that please help.
