# Color of a Metal's Threshold Wavelength?

How do I find the color of the threshold wavelength if the metal has a threshold wavelength of $\mathrm{6.5\times 10^{-7}m}$? I know that converts down to $\mathrm{650\ nm}$, but can I still use the visible color spectrum's wavelengths to find the color or is it different for metal?

I'm sorry I'm new to this and am just making sure it still applies.

Hi Mia. If you're interested in finding colors, then there are many online calculators like this one ;-) –  Waffle's Crazy Peanut Apr 28 '13 at 2:30
