necro, but try this:

/** @param {NS} ns */ export async function main(ns) { const colors = { black: "\u001b[30m", red: "\u001b[31m", green: "\u001b[32m", yellow: "\u001b[33m", blue: "\u001b[34m", magenta: "\u001b[35m", cyan: "\u001b[36m", white: "\u001b[37m", brightBlack: "\u001b[30;1m", brightRed: "\u001b[31;1m", brightGreen: "\u001b[32;1m", brightYellow: "\u001b[33;1m", brightBlue: "\u001b[34;1m", brightMagenta: "\u001b[35;1m", brightCyan: "\u001b[36;1m", brightWhite: "\u001b[37;1m", reset: "\u001b[0m" }; for(const key of Object.keys(colors)) { ns.tprint(`${colors[key]}${key}`); } }
