Have you had enough of the same 16 colors in your terminal?
Welcome to a new world. A new world where colors are plentyful. A world in 256 colors.
// pick a color
var r, g, b uint8
r, g, b = 252, 255, 43
// choose a word
word := "=)"
// colorize it!
coloredWord := rgbterm.FgString(word, r, g, b)
// print it!
fmt.Println("Oh!", coloredWord, "hello!")
Also, to be correct: there are 216 colors and 16 grey scales. For more details, Xterm.
