```

### Arguments

`number r`
Red color component.
`number g`
Green color component.
`number b`
Blue color component.
`number a (nil)`
Alpha color component.

### Returns

`number rb`
Red color component in 0..255 range.
`number gb`
Green color component in 0..255 range.
`number bb`

## Notes

Here's implementation for 11.2 and earlier.

```function love.math.colorToBytes(r, g, b, a)
if type(r) == "table" then
r, g, b, a = r[1], r[2], r[3], r[4]
end
r = floor(clamp01(r) * 255 + 0.5)
g = floor(clamp01(g) * 255 + 0.5)
b = floor(clamp01(b) * 255 + 0.5)
a = a ~= nil and floor(clamp01(a) * 255 + 0.5) or nil
return r, g, b, a
end
```

Where `clamp01` is defined as follows

```local function clamp01(x)
return math.min(math.max(x, 0), 1)
end
```
