why does yellow seem “brighter” than other colors?

Question

why does yellow seem “brighter” than other colors?

Answer 1

I don’t find that to be true. Yellow crayon/marker or digital text is _light_, but not what I would call _bright_; it’s pretty hard to see at all unless the substrate is dark, which is not as true about green or red. (Unless you’re colorblind?)
