Every mode has a parameter that can be adjusted. In most modes, it’s the color/hue, in others it’s the speed/density of the pattern, or the brightness.
To adjust a mode, do a long-press (hold for more than 0.75 sec.) and let go when the indicator flashes. The mode will cycle slowly through its adjustment.
When you see what you like, a button press will stop the adjust cycle, selecting that adjustment.
