what i’m trying to do is I have a midi keyboard with the C,E and G keys assigned as int 255 each, to make a coloured ellipse, what I’d like is that when the keys are released to then remove that color value so the RGB values can be changed and not just ultimately create a white ellipse…?

Have you tried using either note off or keyReleased? I’m not quite clear on your goal from your description.
