# Outline

Outline : `OverlayBase`

## Overview

This instance allows displaying the Outline of a BasePart in a specified color.

Outline and Fill effects added under a character model are not applied to objects under the Humanoid’s ActionRunner, preventing unnecessary effects on ActionSequence presentation objects. This rule applies equally to objects cloned when an ActionSequence is executed and objects dynamically added to the ActionRunner through scripts. However, if Outline or Fill effects are added directly to objects under an ActionSequence, those effects are applied.

## Properties

### Color

`Color3`

The color to display for the outline.

#### Code Samples

```lua
local Outline = script.Parent

Outline.Color = Color3.fromRGB(255, 0, 0)
```

### Thickness

`number`

The thickness of the outline.

#### Code Samples

```lua
local Outline = script.Parent

Outline.Thickness = 10
```
