How to incorporate Ultimate Gray and Illuminating in the kitchen:

1. Consider an area rug. Kitchens tend to be where people gather — and (shoeless) feet feel coziest on carpeting. Black, white, and black and white kitchens get a touch of warmth when an Ultimate Gray-toned area rug is layered on top of tile flooring. Pottery and other table toppers in gray are also easy ways to feature Ultimate Gray in the kitchen.
2. Try an accent wall. Either to give an eat-in kitchen nook its own identity or to enliven one side of the room, a splash of sunny yellow paint serves as an instant mood and design booster.
3. Couple gray with metallic fixtures. To complement gray countertops or tile flooring in a modern way, pick a stainless, chrome or matte black faucet. Metallic drawer pulls can also elevate an all-gray kitchen. 

How to incorporate Ultimate Gray and Illuminating in the bathroom:

1. For a spa-like, serene atmosphere, experts recommend neutral colors, like gray, in the bathroom. Though yellow can be beautiful as an accent to gray, avoid using the shade to paint the whole bathroom; light bounces off it and can do funny things to a person’s skin tone (giving it a greenish cast) when confined to a small, enclosed space.
2. Opt for fresh (or silk) yellow flowers, like daffodils or crocuses, to add a naturally cheerful element to a gray bathroom. 

How to incorporate Ultimate Gray and Illuminating together in your kitchen or bathroom:

1. Finding throw pillows and blankets for banquette seating in the kitchen in both shades is a great way to dip your toe into the gray-and-yellow trend in a soft, natural, yet not necessarily permanent way.
2. Fold yellow hand towels over gray bath towels in a basket or over a rack to give an all-white bathroom a little kick of color.
