COLOR CODE4K8 - Dark Walnut PearlLexus Touch-Up Paint

The Look

This is the definitive "Old Money" color of the early nineties. While most flagship sedans of the era were sticking to flat blacks or predictable silvers, your LS400 was making a much quieter, more sophisticated statement. This shade is deep, earthy, and deceptively complex. In the shade, it presents as a heavy, dark brown that anchors the car to the road. Once the sun hits those long body panels, the depth unfolds. Since your car has been on the road for over thirty years, the original finish has likely mellowed, but a fresh application of Lexus Dark Walnut Pearl (check for code 4K8) brings back that executive library vibe that defined the first generation of Japanese luxury.

Technical Details

Because this is a pearl finish and not a solid color, the way you apply it matters more than the color itself. Pearl paints rely on tiny mica flakes to catch and refract light. If those flakes aren't distributed evenly, the repair will look darker or muddier than the rest of the panel. This isn't a "one and done" application. You are building depth through layers. If you apply the paint too heavily in one spot, the pearls will sink and create a dark blotch. The goal is a uniform, even mist or a series of thin, feathered strokes to ensure the metallic particles stand up and catch the light just like the factory finish did in 1990.

Best Practices

Before you begin, open your driver side door and look at the identification plate in the door jamb. You are looking for the "C/TR" line to confirm your code. To get the best results, you must shake your container for a full minute to wake up those settled pearls. Test the color on the included card to see how the flakes lay down before you touch the car. Whether you are using a 12-ounce container or a small Pen, you must keep the container moving to avoid puddling. Work in your Garage or the Shade to keep the surface cool. Give each layer enough drying time so the next pass doesn't melt the one beneath it. Several thin applications will always look better than one thick one.
