	fmt.Print(c.Yellow("\nThe tree is yellow."))

	// with const
	fmt.Printf("\n%sThe tree is red.%s", c.FgRed, c.FgReset)

	fmt.Printf("\n%s", c.Yellow(c.MagentaBg("The tree is yellow ")+c.CyanBg(" with colorful leafs.")))

		c.BgMagenta, c.FgYellow, c.BgCyan, c.FgBlack, c.BgReset, c.FgReset)
}

• Use colored text

fmt.Print(c.Red("The tree is red."))

• Use colored text on colored background

fmt.Printf("\n%s", c.BlueBg(c.Red("The tree is red with blue leafs.")))

Persistent coloring

If you set color via constant and do not reset it, then the color will persist for the next prints.

	fmt.Printf("\n%sThe tree is red.", c.FgRed)
	// ... some code
	fmt.Printf("\ndone at %v", time.Now().Local())
	// ... some code maybe more prints
	// restore color to normal
	fmt.Print(c.FgReset)
	fmt.Print("\nThe winter is coming, the leaves have fallen.")

All colors

Colors in different terminals

Colors may and will vary slightly depending on the terminals.
