There's the strange phenomenon that people like to say "bright red" as much as it is an oxymoron.

#ff0000 is, in terms of brightness, pretty dark compared to #ffffff yet there is a way it seems to "pop out" psychology. It is unusual for something red to really be the brightest color in a natural scene unless the red is something self-luminous like an LED in a dark night.

It's not. Reds can be dark or bright relative to other reds, and "bright red" -- as you would expect from the way that adjectives work -- refers to a red that is bright relative to other reds.

Right. Just the extremely common cases where humans deliberately use red lights because of the fact that they are perceived as being very bright. Stop lights, brake lights, tail lights, emergency vehicle lights, aviation obstruction lighting, emergency flairs, emergency exit lights, etc.

... have you ever checked if you might be colorblind? Speaking as someone with protanomaly who used to think "bright red" wasn't bright until he got functioning colorblindness-correcting lenses (as I explained in a comment elsewhere in this discussion).
