How can I change the default color of the basic geometric regions in 2D?

I like to use the basic geometric regions in Mathematica, like Parallelogram(…), Rectangle(…), Circle(…), but I don’t like the default solid black color that Mathematica uses when I show the 2D-regions with Graphics(Triangle()).

I like the color for the 3D-regions (light brown/orange), is there a way to use this (or another) color as the default color to the 2D regions?
