The RGB values are a subset of colors in the HSL color space, so they're typically easier to work with when picking colors for web design purposes. In addition, you can also get RGB (red, green, blue) values and HSL (hue, saturation, lightness) values. With a simple image provided, you can choose a color and get the corresponding 6-digit code. The color picker is an easy way to get hexadecimal values of a color.
