# Background

Backgrounds are automatically converted to text display entities when possible (**1.19.4**+), in those cases transparency is supported. Transparency can be defined as an **r g b a** color value, for example `color: 255 0 0 128`.

```yaml
  ## object name, you can set this to anything that is unique
background1:
  ## object type, in this case background
  type: background
  ## x and y positions relative to the parent
  position: 0 0
  ## width and height of the object
  size: max max      
  ## color of the background
  color: white
```
