There are a few factors that make matching color a difficult task. First let’s take a look at what makes up the paint. The basic ingredients in automotive paint are resin, pigment, and solvent. Resin holds together the pigment, provides adhesion to the surface applied, and determines the quality and paint durability. Pigment comes in powder form, and the aftermarket auto paint mixing system includes roughly 100 colors or toners to mix formulas, including pearl and metallic paint colors. Solvent provides transferability; without it the paint would be too thick.
When the auto paint manufacturer mixes these three elements to create a formula for the standard color, they are allowed a tolerance of plus or minus 5% when the paint is delivered. This percentage can make a big difference and actually cause two of the same vehicles to look completely different in color.
Temperature when painting, paint film thickness, time between coats, speed and type of paint spray gun, surface type, and humidity can all factor in differences in auto body paint color shade.
Sunlight is another factor to consider when color matching. A car exposed to sunlight for years will have begun to fade in color.
