I have very fair combination skin and I use the pink shimmerbrick (the "rose" one is really pink, while the "pink" one, ironically, is really subtle).
I use all colors together with a large brush and use it as cheek highlighter (e.g. the area beside the nose and under the eye), cheekbones). It looks like a subtle glow and not at all like oily skin when you use it where skin normally does not get shiny. Also looks great on photos.
