Just a few suggestions:
Instead of the colour changer icon looking like a PAR can, it would be nice to have a picture of a scroller.
A new icon for LED fixtures (such as LED PAR cans and similar) indicating the multicolour capabilities of most of these devices.
A new icon for rotators - gobo rotators, glass disc effects projectors, mirror ball rotators etc.
