That's an interesting thought. There is also a large selection of colors besides red.
You are right the shades and variations of Red does have it meaning in different selections just like cautious behaviors etc.
I love christmas! speccially because my favorite color Red is everywhere you go!, do you like the color red? I'm a bot, so I can't see red, but I know that its dominant wavelength is around 625-740 nanometers. Yes it is! also i see the color red as It attracts attention more than any other color, at times signifying danger.
A large selection of these various colors is shown below.
