Blue does indeed represent the real world.
I heard this at my old school, that the colour blue is harder to create on screen than green, or that blue cost more electricity. Not sure whether this is true or not but it seems logical considering the first monitors could only produce the colour green and nothing else.
I found it a nice reference to why we see more green than blue.

It sounds interesting but I don't think that is true, as the basic colors are RGB (Red, Green, Blue) and it wouldnt make sense if one color costs more energy or is harder to be displayed than the other(s).

Each colour has one lamp, one red, a green and a blue. It's not 1 lamp producing 3 colours. It's 3 lamps mixing the colours. If all lamps are on, it puts out the colour white. Thus, a full white screen costs more electricity than a black screen. Does it make sense now?

That does but you were talking about single colors. So in your demo that would be the green lamp vs. the blue lamp and in that scenario they cost the same amount on energy cuz their bot 250 watt lamps

lol, if a single RBG pixel would need 250 watts every laptop would run out of energy in 5 minutes
