The master section on/off ‘power’ button in Wavelab uses shades of green and red that are very difficult to differentiate the ‘on’ and ‘off’ states.
It would be much better (IMO, as a colourblind person, and generally) if the power button was ‘illuminated’ for on, and a grey colour for off. This would be good for those of us who are red/green colourblind (who, let’s not forget, is around 6% of the male population), and for anyone else with any colour vision issues.
I currently often have to change states several times to know where I’m at with it.
