You really need to study up on/get an educatipn about what exists in the real world re: lasers.Other than Red, Green, Blue, and Violet. Are there other colors that lasers can come in?
Yeah, the visible spectrum runs from 400nm up to 700 nm. In between these two points are all the yellows, teal, orange, blues in most every color range, but being monochromatic they can't be combinations of wavelengths like purple. No one person's perceived color for a wavelength can be said to be a certain color as everyone perceives these wavelengths differently.
