Best exterior paint color for rentals?

[Sam Leon]

I am about to repaint the exterior of a 4 unit apartment building.  Single story, concrete block stucco exterior.

Trying to decide what color to use.

Being in south Florida, we get lots of sun, rain and wind.  Once a coat of paint goes on, within 2-3 years the color changes.  The higher walls shaded by the eaves remain the same color, while the lower walls that gets the sun gets lighter and lighter.  The north side fades differently then the south side, so in a few years you can no longer match the color because you end up with eight different shades of colors.

I am not sure if this can be avoided by using a very light color like white or almond, but it is one consideration.

What color will wear the best, and the most abuse resistant?  If there is such a thing.
