### Electromagnetic Spectrum: Colors

If a wavelength value falls exactly in between two values for two colors on the electromagnetic, what would it be classified as? (e.g. if a wavelength is 500 nm, is it considered green or blue?)

I'm not completely sure how scientists would officially classify it, but I believe that each human sees light slightly differently depending on their biology. The exact wavelength range for each color is an approximate because some people (and languages!) define the threshold between color in different ways. So 500 nm might be a greenish-blue color and some people consider it green and others blue.

There aren't clear-cut boundaries between specific colors; but rather, they overlap and blend together. So, 500 nm would be blue-green, or a sort of teal color. Other colors on the spectrum might be mostly blue but a little green, or mostly green but a little blue. And people might classify colors differently due to their own perceptions.

It'll probably fall in between the colors blue and green, giving it a cyan color.
