Apple watch face updates

I know there are a lot of apps out there for watch faces, but there are some changes to the base apple watch faces that could make an impact for users. There should be options to change the colors on all the faces - For example, in the infograph faces, if you move to any colors besides white or black the complications turn white, why? There should be options to leave the complications as the color they are for the white or black options but I should have the option to make the whole background green or purple. Will there be changes to allow us to better modify our watch faces?
