Color

Beaver comes with the color sub-package that can be used even without Beaver calls.

Color is an interface that simply needs Format(text string) string to fulfill it.
Any logger in beaver can be set to a Color.

Formatting a string with a single attribute

text := color.FgRed.Format("red")

Formatting a string with a full color

text := color.New(color.BgGreen, color.FgRed, color.Bold).Format("green background, red text, and bold")

Extended colors

Extended colors are 256-color extensions. They can be referred to by name, available in extended_colors.go.
