I’ve heard that monitors and TVs can’t display every possibile color that humans can see. What’s stopping them from just having red, green, and blue pixels, and then just making those go as bright (and as dark) as possible? What’s the limitation?
In: Technology
Because despite what you may have been told, you cannot generate every visible colour from a finite set of primaries. Saying that red, green and blue are the primary colours of light means that they’re the optimal choice for generating as large a spread of colours as possible (assuming you’re limiting to yourself to three, which you don’t have to: Sharp’s Quattron LCD screens use four primaries, red, green, blue and yellow). It doesn’t mean that they are fundamental in the way that elements are the fundamental components of chemicals.
