Sometimes we describe a color other then it might being red, blue or green. Sometimes we use daily words or connect them with a color. Something like darkblue, or peach.
The RGB colour model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue
using RGB triplets. i.e. #ff0000, #ffff00, #00ff00. Each set of two characters represents the colors Red, Green, and Blue respectively.
