Can you see?
said it involved violet
was expecting purplish-red, vegetation-green, and an ultramarine-blue
famously got it right.
But what?

Thomas Young originally proposed red, green, and violet, Helmholtz proposed “a slightly purplish red, a vegetation-green, slightly yellowish, and Maxwell changed young’s violet to blue;

each one was trying to get the three primary colours
Thomas Young(1) originally proposed red, green, and violet,
Hermann Von Helmholtz(2) proposed “purplish-red, vegetation-green, and an ultramarine-blue” and
James Clerk Maxwell(3) got it right(RGB).

That cone theory is not entirely consistent, not sure if the three colour model holds good now.

Primary colors
2) Hermann von Helmholtz
3) James Clerk Maxwell
The subject discussed here is the three primary colors
1. Thomas Young, originally proposed the three primary colors as “red”, “green” and “voilet”
2. Hermann von Helmholtz proposed “a slightly purplish red, a vegetation-green, and an ultramarine-blue” as the colors
3. James Clark Maxwell,three-color method was eventually proposed by him with “red”, “green”, “blue” as the colors
