The mask is applied using binary AND. The mask is applied using binary AND.
#### `[colorize:<color>` #### `[colorize:<color>:<ratio>`
Colorize the textures with the given color. Colorize the textures with the given color.
`<color>` is specified as a `ColorString`. `<color>` is specified as a `ColorString`.
`<ratio>` is an int ranging from 0 to 255, and specifies how much of the
color to apply. If ommitted, the alpha will be used.
