why is Violet apart of the light spectrum when it looks identical to purple, but purple isn’t considered part of the spectrum?

Question

I never knew the difference between purple and violet, all I know is that purple, pink, magenta,etc are the “colours” we see when our red and blue cones are activated at once. But Violet is considered a part of the light spectrum? They look the same to me.

Answer 1

Purple and violet aren’t actually the same. Purple is violet plus red.

But yes, the difference is subtle.
