			),
			tui.HStack(
				tui.String("Red").FGColor(color.RGB(255, 0, 0)),
				tui.String("Green").FGColor(color.RGB(0, 255, 0)),
				tui.String("Blue").FGColor(color.RGB(0, 0, 255)),
			).

				Border(tui.BorderOptionFGColor(color.RGB(200, 100, 200))),
		).RelativeSize(10, 10)
	})
	if err != nil {
		panic(err)
	}
}
