Parasol Paints in Toronto, Canada (www.parasolinc.com) will custom-mix a vinyl paint to perfectly match your color. Send them a small sample of vinyl from the underside of a seat or cut from the back hem of a trim panel. A 1/2-inch square will do. You'll need 1 qt. to do the dash and centre console (estimated cost of US$100/qt, shipping extra). I had them mix up two quarts the match my butterscotch seats (sourced from Banzai). The color match was spot on, the product applied very nicely, and it has held up very well over the years (no lifting or peeling). Parasol's vinyl paint is applied with a standard-issue HVLP spray gun. It's water-based and the gun cleans up easily, provided that you do this right after you finish spraying). You'll need to apply at least 3 medium coats to cover a black surface with a light brown paint.
Regardless of whose vinyl paint you end up using, you will need to be relentless in your prep work. All traces of silicone (ArmorAll, etc) need to be removed or else you will get major 'fish-eye' when you try to apply the paint (and you can't just wipe the crazed vinyl paint off and start over again). SEM offers a pair of cleaning products for a two-step process. Effective (if used properly), but not cheap. Parasol offers their own line of cleaners.
