Unity Color Class
The color class is unity is based off an RGBA model, where the values for red, green, blue, and alpha(transparency) are specified with float values between 0 and 1. An alpha of 0 is completely transparent, while 1 is fully opaque. A color can be created with or without the alpha value specified.
Creating a color in CSharp:
public Color myColor = new Color(.2f, .3f, .4f); public Color transparentColor = new Color(.2f, .3f, .4f, 0);
var myColor : Color = Color(0.2, 0.3, 0.4,); var transparentColor : Color = Color(0.2, 0.3, 0.4, 0);
