<description>
A color is represented as red, green and blue (r,g,b) components. Additionally, "a" represents the alpha component, often used for transparency. Values are in floating point and usually range from 0 to 1. Some methods (such as set_modulate(color)) may accept values &gt; 1.
You can also create a color from standardised color names with [method @GDScript.ColorN].
You can also create a color from standardised color names with Color.ColorN (e.g. Color.green) or [method @GDScript.ColorN].
