Consider the type of siding when choosing colors. Aluminum siding can get very hot when painted dark colors, and dark-colored paint can warp vinyl siding. Don't choose paint colors that are any darker in shade than the original vinyl.
Research the original colors for your mobile home, or ones like it. Many aluminum mobile homes were unpainted except for a single stripe. Common vintage colors for mobile homes included light green, white, teal and pink.
Test prospective colors by painting samples directly onto your mobile home before purchasing all the paint. It can be difficult to predict how colors will look simply by looking at the little color swatches.
Use two coats of 100-percent acrylic exterior paint no matter what type of siding you have. It will last longer than latex or vinyl paint when applied to a properly prepared, primed surface.
