		Color in RGBA format with some support for ARGB format.
	</brief_description>
	<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].

				Constructs a color from an HTML hexadecimal color string in ARGB or RGB format. See also [method @GDScript.ColorN].
				The following string formats are supported:
					[code]"#ff00ff00"[/code] - ARGB format with '#'
					[code]"ff00ff00"[/code] - ARGB format
					[code]"#ff00ff"[/code] - RGB format with '#'
					[code]"ff00ff"[/code] - RGB format
				[codeblock]
				# The following code creates the same color of an RGBA(178, 217, 10, 255)
				var c1 = Color("#ffb2d90a") # ARGB format with '#'
				var c2 = Color("ffb2d90a")  # ARGB format
				var c3 = Color("#b2d90a")   # RGB format with '#'

				[codeblock]
				var bg = Color(0.0, 1.0, 0.0, 0.5) # Green with alpha of 50%
				var fg = Color(1.0, 0.0, 0.0, .5) # Red with alpha of 50%
