THE COLOR IS VERY BRIGHT.
Very poor quality. Pen worked for about 11/2 inches then stopped. Had to put lid on, shake and re-prime continually, than a big blob of paint comes out. White is way too bright. Much brighter than standard white grout and standard white tiles. So your job is patchy, but pen not working to do all tiles. Postage took 2 months. I do not recommend this product.
