<a id="syntaxSection" />

## Syntax

```cpp theme={null}

{
    uint8_t r;
    uint8_t g;
    uint8_t b;
    uint8_t a;
};
```

### Members

*r*\
Type: uint8\_t

The red channel value of the color.

*g*\
Type: uint8\_t

The green channel value of the color.

*b*\
Type: uint8\_t

The blue channel value of the color.

*a*\
Type: uint8\_t

The alpha channel value of the color. This represents the relative transparency of the color, where zero is fully transparent and 0xFF is fully opaque. If an alpha value other than 0xFF is used, the color will undergo an additional blending step against black. To avoid this blending step, do not pass in any alpha value other than 0xFF when setting colors.
