Questions on brightness of old colour TVs

[Carmine]

Old TV Nut, you were right... Long read! But very, very interesting!

I really don't know how they can say what any color "looks" like, since you can only describe a color by relating it to another... In other words, imagine trying to explain "blue" to a person who has been totally blind all thier life? It would be like trying to explain a mythical color like "koorange"* to anyone else.

This is making my head hurt.

*If I ever invent anything, I'm going to name it "koorange, plahboragne, etc" because I want to ruin that rule about "nothing rhymes with oragne".
