Property of [`MaterialSpec`](MaterialSpec.md) · inherited by [`MaterialInput`](MaterialInput.md) · stable · since 2.0.0

```ts
exactColor?: boolean;
```

Lit, but skips exposure and the tone curve, so white stays white (backdrop walls).

**Default:** false

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `exactColor` names no product |
| 2. A precedent | pass: [Babylon.js ImageProcessingConfiguration (per-material opt-out)](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Materials/imageProcessingConfiguration.ts) (row `E4`); [glTF KHR_materials_unlit](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_unlit) (row `K12`); [Babylon.js PBRMaterial.unlit](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Materials/PBR/pbrMaterial.ts) (row `K12`) |
| 3. Two apps, or labs | pass: 5 apps (ledger: app-0c773a4ee3, app-b362a81c85, app-b4ae2fce25, app-ddfb017681; fleet cross-check: app-fc07850558) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `E4`, `K12` at tier stable (a member only where no rule, data, asset or app code serves the need) |
