# Light Blend Styles

In the [2D Renderer Data asset](2DRendererData-overview.md), its **Light Blend Styles** determine the way that the light interacts with sprites in the scene. The asset can contain a total of four different **Light Blend Styles**, each with a different combination of Blend Style settings by default. All lights in the scene must pick from one of these available **Light Blend Styles**. When you create a light, it's automatically assigned the first Blend Style listed in the asset.

## Mask Texture Channel

A mask controls where lights can affect a sprite. For this property, select which channel(s) of the mask texture will affect the sprite it's masking. These channels comprise the red green blue alpha (RGBA) color model.

## Blend Mode

This property determines how Unity blends the lighting with the colors of the sprite and other GameObjects that the light affects. The following are some examples of how a mask affects the sprite its covering with different **Blend Modes**.
