made a slight modification to your code below, which should give the same
clour output for volume, but it instead it plots black for green & light
grey for red. The boolean _expression_ for direction should resolve to 1
(true) or 0 (false) and Volcolor should plot the same as you original code.
Can you why this is not the case ?

Just make a formula out of it and drag and drop onto the price all in one
screen.
