Description

Sets the color used to fill shapes. For example, if you run fill(204, 102, 0), all shapes drawn after the fill command will be filled with the color orange. This color is either specified in terms of the RGB or HSB color depending on the current colorMode(). (The default color space is RGB, with each value in the range from 0 to 255). The alpha range by default is also 0 to 255.

If a single string argument is provided, RGB, RGBA and Hex CSS color strings and all named color strings are supported. In this case, an alpha number value as a second argument is not supported, the RGBA form should be used.

A p5.Color object can also be provided to set the fill color.
