const callBackFunction = (keyValue: string | undefined, key: any) => {
  if (key.name && key.name == "return") return true;

Color static method

use Color

import { Color, _p } from 'a-node-tools';

_p(
  `${Color.red(
    `Red start${Color.yellow('The middle is yellow')} and the red ending`,
  )}`,
);

_p(Color.random('Randomly print a string of color values'));
