# PhysicallyBasedMaterial.BaseColor

An object that defines an entity’s base color.

```
struct BaseColor
```

## Overview

Use this struct to specify an entity’s base color, which defines the
entity’s appearance before RealityKit calculates the effect of lighting
or material properties such as
[`roughness`](/documentation/RealityKit/PhysicallyBasedMaterial/roughness-swift.property) or
[`metallic`](/documentation/RealityKit/PhysicallyBasedMaterial/metallic-swift.property). For more
information, see [`baseColor`](/documentation/RealityKit/PhysicallyBasedMaterial/baseColor-swift.property).

## Topics

### Creating a base color object

[`init(tint:texture:)`](/documentation/RealityKit/PhysicallyBasedMaterial/BaseColor-swift.struct/init(tint:texture:)-2wriz)

Creates a base color object from a color or texture on macOS.

[`init(tint:texture:)`](/documentation/RealityKit/PhysicallyBasedMaterial/BaseColor-swift.struct/init(tint:texture:)-5jeqr)

Creates a base color object from a color or texture on macOS.

[`init(_:)`](/documentation/RealityKit/PhysicallyBasedMaterial/BaseColor-swift.struct/init(_:))

Creates a base color object from a custom material’s base color
property.

### Accessing texture data

[`texture`](/documentation/RealityKit/PhysicallyBasedMaterial/BaseColor-swift.struct/texture)

The base color as a UV Image map.

[`textureSemantic`](/documentation/RealityKit/PhysicallyBasedMaterial/BaseColor-swift.struct/textureSemantic)

The intended use of this object’s texture property.
