# Palette class

Namespace: [Eto.Drawing](https://eto.picoe.ca/api/namespace/eto.drawing.md) · Assembly: [Eto](https://eto.picoe.ca/api/assembly/eto.md)

```cs
public class Palette : ObservableCollection<Color>, ICloneable
```

Represents a collection of [Color](https://eto.picoe.ca/api/type/eto.drawing.color.md) objects

**Remarks:** Typically used for [IndexedBitmap](https://eto.picoe.ca/api/type/eto.drawing.indexedbitmap.md) or other purposes where a collection of colors is needed. This class keeps a cache of 32-bit ARGB values for each element in the collection for faster retrieval. These values are generated using [Color.ToArgb()](https://eto.picoe.ca/api/type/eto.drawing.color/toargb.md).
