I find that medium red, medium green and light blue are all pretty close
to 18% gray in terms of reflectivity. Get a gray card and go outside and
experiment with meter readings of various colors and the gray card
reading. It doesn't take long to develop a feel for what the degree of
reflectivity you can expect from various colors and surfaces.
