Color in RGBA format using floats on the range of 0 to 1.
</brief_description>
<description>
A color represented by red, green, blue, and alpha (RGBA) components. The alpha component is often used for transparency. Values are in floating-point and usually range from 0 to 1. Some properties (such as CanvasItem.modulate) may accept values greater than 1 (overbright or HDR colors).

You can also create a color from standardized color names by using [method @GDScript.ColorN] or directly using the color constants defined here. The standardized color set is based on the [url=https://en.wikipedia.org/wiki/X11_color_names]X11 color names[/url].
If you want to supply values in a range of 0 to 255, you should use [method @GDScript.Color8].
[b]Note:[/b] In a boolean context, a Color will evaluate to [code]false[/code] if it's equal to [code]Color(0, 0, 0, 1)[/code] (opaque black). Otherwise, a Color will always evaluate to [code]true[/code].
