Red is less visible cause it's the color lowest on the visible light spectrum, one stop lower is infrared - nonvisible light.
Red may stand out against light colors in the daytime, but it's harder than black to see in low-light conditions.
I wonder if green and blue are easier to see being high on the visible spectrum? Or whatever is right in the middle?
