Yellow is my favorite color it reminds me of the sun
It's very pretty, its between green and orange in the color spectrum.
Yes its a primary color and noticeable so its often used for cautionary signage
That makes sense. Carotenoids are what makes corn and lemons and daffofils their yellow color.
I have noticed the color yellow will fade if exposed to direct sun daily
There was an episode of The SImpsons called "The Color Yellow" too, it recieved mixed reviews though.
