 A color intermediate between blue and red is purple
That's interesting. I didn't know that is what it's called. What else can you tell me?
unlike violet, which is a spectral color with its own wavelength on the visible spectrum of light, purple is a composite color made by combining red and blue.
I had no idea that violet was so different. 
On the screens of computer monitors and television sets, a color which looks similar to violet is made, with the RGB color model
It's interesting how they can even get all the colors like that on screens with limited led colors
Interestingly,purple is the color most often associated with royalty, magic, mystery and piety.
Does it give off any emotional response? It does make sense it's associated with those things.
combined with pink, it is associated with eroticism, femininity and seduction.
