Getting the right HSB value only gets you the base color. Matching the finish is a separate decision, and it's the part that actually sells the illusion up close.
Real automotive paint isn't just a color, it's a color plus a physical structure that decides how light bounces off it. Forza's finish options exist to approximate that structure. Here's what each one is actually doing, and which real-world finish it's meant to represent.
| Real finish | What it physically is | Closest Forza setting |
|---|---|---|
| Solid / gloss | Flat color under a clear gloss coat, no metal or mica added | Normal |
| Metallic | Tiny aluminum flakes suspended in the clear coat, reflect light without shifting color | Metallic |
| Pearl / mica | Ceramic crystals that refract light, causing the color to shift depending on viewing angle | Pearl |
| Metal flake | Larger, chunkier metal particles than standard metallic, more visible individual sparkle | Metal Flake |
| Matte | No clear gloss topcoat, light scatters diffusely instead of reflecting sharply | Matte |
| Chrome | A mirror-like vacuum-metallized layer, reflects almost like a mirror rather than showing a color | Chrome |
Base color first, finish second
Your Hue, Saturation, and Brightness values don't change based on finish, that's the color itself. Get those right using the paint-matching guide first, then come back and set the finish. Doing it in the other order just means redoing the color once you notice the finish changed how it reads.
How to tell what finish your car actually has
Check the color name first. Manufacturers usually put the finish right in the name, "Pearl White," "Metallic Blue," "Matte Black." The OEM color lookup will show you the full name from your paint code, and that's often all you need.
If the name doesn't say, look at the car in direct sunlight. Sparkle with no change in color as you move around it is metallic. A shift in shade or hue depending on the angle is pearl. A dull, non-reflective surface with no shine at all is matte.
A note on accuracy
Forza's rendering is an approximation, not a physics simulation of real paint. Lighting in-game will make any finish look somewhat different than it does in a parking lot. Don't chase a pixel-perfect match, get the base color exact and the finish category right, and it'll read correctly at a glance, which is what actually matters.
