toAnsi.fromColor("green");                       // => \x1b[38;5;46m
toAnsi.fromHsl({hue: 0.5, saturation: 0.5, lightness: 0.5})

Apply colors to the console via the fromHexa function

console.log(
    toAnsi.fromHexa("#00FF00") +                        // Green text
    toAnsi.fromHexa("#FF0000", false) +                 // Red background (false = background)
    toAnsi.STYLE.Underline +                            // Underline text
    toAnsi.STYLE.Bold +                                 // Bold text
    "Okay" +                                            // Text to display
    toAnsi.RESET                                        
);

Apply colors to the console via the getText function (Recommended way)

// Yellow
console.log( toAnsi.getTextFromColor("Hello you!", {fg: "yellow"}) );

// Yellow with blue background
console.log( toAnsi.getTextFromHex("Hello you!", {fg: "#FFFF00", bg: "#0000FF"}) );

// Yellow-ish on purple-lish
console.log( toAnsi.getTextFromHex("Hello you!", {fg: "#FFCCFF", bg: "#DD00FF", isUnderline: true}) );
