Overview
The Color Detector is a component that can be used to detect a specific color with tolerance.
A Color Detector analysing three cubes for a Red color. The Output Signal returns High for the red cube, and low for the green and blue cubes.
Where to find
The Color Detector Physical and Logic components can be found under Standard Components > Color Sensor > Color Detector.
It can be accessed from the GameObject menu as well as from the Hierarchy Context menu.
A new GameObject will be created if you do not have a GameObject selected. Otherwise, the Color Detector will be added to the selected GameObject.

Match Percentage | The percentage with which the detected color matches the Reference Color. |
Properties | |
Color Sensor | The specific Color Sensor to use for the Color Detector. By default, a |
Reference Color | The color which the detected color will be compared with. |
Threshold | The minimum Match Percentage at which the Color Detector has a High Output Signal. |
On Signal High | A UnityEvent that is fired as soon as the Color Detector has a High Output Signal. |
On Signal Low | A UnityEvent that is fired as soon as the Color Detector has a Low Output Signal. |
