I did find it impossible to read at the default speed/size at 1 meter away. However from 4 meters and further, the default speed/size is fine.
Also, since red has the longest wavelength, it is more visible at a distance - just as the red of a traffic light can be seen further away than the green. Having the option to change speed/size/color would be useful though.
