Colours
When you need to specify a colour, picamzero can accept colours in one of three formats:
RGBA
A tuple containing a colour code in RGB format plus an alpha (transparency) value. For example, red would be:
(255, 0, 0, 255)
The first three values are Red, Green and Blue (0-255) and the final value is the transparency, with 0 being fully transparent and 255 being fully opaque.
Hex colour code
You can specify any valid hex code for a colour, in the format #000000.
Colour name
The following colours can be specified by name as a string:
