create a triangular figure

I have a plate where I want to punch a rounded triangle into (will become a socket).
The problem is that I can hardly use triangles because of the subsurf modifier I need. Unfortunately quads do not really seem to work either; at least not the way I used them.
Does anybody know a good way to create such a shape?

the upper shape is created with triangles, the lower one with quads

see pic

bit i think that subsurf will create a problem of color bleeding !
so if anybody knows how to get rid of this color bleeding let us know !

Have to add another edge close to the transition of the two surfaces to further constrain the shape and material. There’s not really a bleed, just a curving of the surface during subdivision.

Sorry, I don’t understand what you mean.
Could you please post a screenshot of your mesh or explain what you mean with this sentence?
