No. Red is a single wavelength, we call red to anything that emits light waves with length between 625 to 750 nanometers, green anything between 500 to 565 and blue anything 450 to 485.
White is not real, white is what your eyes percebe multiple wavelengths together, if we had evolved near a red dwarf, there would probably be less blue light so out white would likely be independent of blue, just like it is independent of UV currently (because we don’t see those wavelengths).
Curious thing is that purple is also not real, purple is what your brain interprets blue+red, which are two separate wavelengths, so it’s not a color like red or green, but rather an illusion that your brain creates to show you red and blue at the same time.
