That's interesting. As for red, the red range goes from yellow-tinted scarlet to blueish crimson, and in darkness it goes from pink to the dark burgundy.
Yep - approximately 380-450 nanometers.  Red has so many variations also, from yellow tinged to bluish-red to red pink and even burgunday.
Red is such a passionate, vibrant color Oh, that's nice. It sits next to orange at the end of the spectrum of visible light. It has the longest wavelength from what I can remember! I don't know if it's the longest, but its dominant wavelength is around 625-740 nanometers. That's long, I guess! I know that violet has short wavelengths.
Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy.
