Red is such a passionate, vibrant color

It really is!  My kitchen is actually red - it's at the end of the visible spectrum of light next to orange and opposite violet.

It has the longest wavelength from what I can remember!
1_Wizard
It does - you are smart!  The wavelength is 625-740 nanometres!

That's long, I guess! I know that violet has short wavelengths.
1_Wizard
Yep - approximately 380-450 nanometers.  Red has so many variations also, from yellow tinged to bluish-red to red pink and even burgunday.
