What color represents confidence and self respect and why?

Yellow represents confidence and self respect. The color yellow relates to acquired knowledge. It is the color which resonates with the left or logic side of the brain stimulating our mental faculties and creating mental agility and perception.
I hope this helps.

White, it's pure and kind-hearted. just like your confidence and self respect :)
