If you're looking for the paint code for iridescent pearl Tricoat, it's likely that you're trying to touch up a car that has this paint color. Iridescent pearl Tricoat is a special effect paint color, meaning that it's not a solid color like most other paint colors. Instead, it contains tiny flakes of mica or metal that reflect light and create a shimmering effect.
The actual color of iridescent pearl Tricoat can vary depending on how the light hits it, but it typically appears as a light silver or gray. If you need to match this exact color when touching up your car, your best bet is to take it to a professional automotive painter who can mix the custom color for you.
Alternatively, if you're painting an entirely new car or doing a full respray, there are many iridescent pearl paints on the market that come in aerosol cans or quarts. These will typically give you a more consistent result than trying to mix your own custom batch of paint.
