How to use the ansi-colors.grey function in ansi-colors

// If this is false, stream was changed since validation
		if (erroredLine) {
			var errorColumn = message.lastColumn;

			// Trim before if the error is too late in the line
			if (errorColumn > 60) {
				erroredLine = erroredLine.slice(errorColumn - 50);
				errorColumn = 50;
			}

			// Trim after so the line is not too long
			erroredLine = erroredLine.slice(0, 60);

			// Highlight character with error
			erroredLine =
				colors.grey(erroredLine.substring(0, errorColumn - 1)) +
				colors.bold(colors.red(erroredLine[ errorColumn - 1 ])) +
				colors.grey(erroredLine.substring(errorColumn));
		}

		if (typeof(message.lastLine) !== 'undefined' || typeof(lastColumn) !== 'undefined') {
			fancyLog(type, file.relative, location, message.message);
		} else {
			fancyLog(type, file.relative, message.message);
		}

		if (erroredLine) {
			fancyLog(erroredLine);
		}
