Any body shop or auto parts store that sells automotive paints should have the ability to match that color.
Your particular RW was the early non painted version, the later non painted were tan & black for a year or so then they did not offer an unpainted unit all were full body paint.
Just FYI unless you've had a the front/rear caps painted due to fading they ARE NOT painted, the color is infused in the gelcoat & if faded the only sure cure is to have them painted with automotive paint. Same as the sides, the tan is a colored decal, the white is color infused fiberglass. The J panel along the bottom is colored aluminum, not sure how it's colored, possibly powder coated.
