The color violet has a wavelength range that starts at 400 nanometers and ends at 450 nanometers. Since 430 nanometers is inside of this range, 430 nm denotes some shade of the color violet.
450nm is a royal blue color, (a sort of purple-ish color similar to that of a Crown Royal bag). For reference, lower number values are closer to the ultra violet spectrum, whereas the higher a number value, like lets say 808nm, the closer it is to the infrared spectrum. If you're looking at buying a laser that has a 450nm output, chances are that the seller is trying to pass it off as the popular 473nm, (which is that brilliant beautiful sapphire blue that you see in police lights and the blue indicator LED on most bluetooth devices). The 450nm lasers are usually much cheaper, as the beam comes right out of the diode at that color without having to be pumped through the expensive optics like what is required to get a beam at 473nm. If you prefer royal blue as apposed to the sapphire blue, then you're in luck, otherwise, you may be disappointed to see a nearly purple beam when you get your laser... Sorry if this is a bit too detailed, but usually questions about wavelength that I come across are in reference to laser or LED colors.

If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.
The wavelength for the color red is 700-635 nm, which can also be said as 700 to 635 nanometers.
Purple is a mixture of the colors red and blue.
Approximately in the range of 350-700 nm, depending on the color.
Here you have the frequencies of BLUE and colors next to it:violet380-450 nmblue450-475 nmcyan476-495 nm
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.
The color is red.

Originally, CD lasers with a wavelength of 780 nm were used, in the infrared.For DVDs, the wavelength was reduced to 650 nm (red color), and the wavelengthfor Blu-ray Disc was reduced to 405 nm (violet color).
Blue
This is the violet color (380-450 nm).
Blue is part of the colour spectrum, with a wavelength of about 475 nm.
The wavelength for the color red is 700-635 nm, which can also be said as 700 to 635 nanometers.
The wavelength of the color violet is 450-400 nm, which can also be said as 450 to 400 nanometers.
The standard wavelength for the color green is 560-490 nm, which can also be said as 560 to 490 nanometers.
Purple is a mixture of the colors red and blue.
670.8 nm is the wavelength.
