Steps to reproduce this

https://p5js.org/reference/p5/background/
the docs state an overload for background() is:
background(colorstring, [a])
where:
colorstring
String: color string, possible formats include: integer rgb() or rgba(), percentage rgb() or rgba(), 3-digit hex, 6-digit hex.
a
Number: opacity of the background relative to current color range (default is 0-255).
which would imply this would work:
background('#222222', 127);
yet it doesn't
