# VFX type reference

This page references all the types the Visual Effect Graph uses. Some of these are standard C# and Unity types whereas others are unique to the Visual Effect Graph.

## Base types

Base types refer to standard C# and Unity types that you can use to store basic data.

### Attribute-base types

Attribute-base Types are types that you can use for new attribute storage in Blackboard's corresponding tab section.

## Advanced types

This section describes the advanced types that the Visual Effect Graph includes. These are either advanced versions of the base types or composite types (made up of multiple properties).

### Spaceable base types

Spaceable base types are Vector types that embed a space alongside their value. They also use a vector semantic when performing space transformations.

| **Type**      | **Color**                                                     | **Description**                                              |
