How to use the @parcel/logger.color function in @parcel/logger

function pipeSpawn(cmd, params, opts) {
  const cp = spawn(
    cmd,
    params,
    Object.assign(
      {
        env: Object.assign(
          {
            FORCE_COLOR: logger.color,
            npm_config_color: logger.color ? 'always' : '',
            npm_config_progress: true,
          },
          process.env,
          {NODE_ENV: null}, // Passing NODE_ENV through causes strange issues with yarn
        ),
      },
      opts,
    ),
  );

  cp.stdout.setEncoding('utf8').on('data', d => logger.writeRaw(d));
  cp.stderr.setEncoding('utf8').on('data', d => logger.writeRaw(d));

  return new Promise((resolve, reject) => {
    cp.on('error', reject);
    cp.on('close', function(code) {
