Why do we use the color red to signal stop?
Red has longest wavelengths we can perceive with our eyes.
Longer wavelengths are infrared waves, microwaves and radio waves.
We can’t see these longer waves, but can we sense them?
I often wonder if we can feel red somehow.
When it is mixed with other colors it demands our attention.
When it’s bright and big it makes us pause.
What does red light beaming at us feel like subconsciously?
Why does it universally mean stop?
Do we all have an ancient memory of blood red danger?
Does red make some of us blush and make others feel angry?
How does red make us feel?
