Which wavelength range corresponds to blue light?

Explanation:
Light color is tied to wavelength, with the visible spectrum spanning roughly 400 to 700 nanometers. Blue light sits on the shorter-wavelength end, around 450 nm, so a range that lies within about 430 to 480 nm matches blue most closely. The 400–430 nm band trends toward violet, while 480–560 nm shifts toward blue-green and green, and 590–630 nm is red-orange. So the 430–480 nm range best corresponds to blue light.
