Firmament is a medium, cool blue with steely blue undertones that give it a restful quality. With an LRV of 37, it adds character to a space without overpowering it, working well in home offices, mudrooms, and powder rooms. The closest cross-brand match is Behr's Whale Gray, with only a slight difference visible side by side. Kilz's Tempest is another strong alternative.
