Being colour blind, this is something I'd love to see in a future update. My most frequent changes are boosts/distortions and delays and to be able to make these easier to see would be very helpful. For example, I sometimes struggle to differentiate between reds and oranges and greens and yellows. If I could change the distortion block to blue and the delay block to white for example, it would be easier to spot at a glance in a live situation.
