Astronomical (#334142) by Behr is a deep gray paint color with a gentle, subdued character. It delivers a grounded richness that adds drama and sophistication. On the temperature spectrum this shade carries a cool cast, lending calm and collected elegance. Its RGB channels are closely balanced, contributing to its neutral, even-keeled visual character. At an LRV of 24 it absorbs more light than it reflects, creating a moody, enveloping atmosphere. Deep neutrals like this create contrast and gravitas on accent walls, exterior facades, and kitchen cabinetry, pairing well with lighter trim. Satin or semi-gloss finishes help deep colors reflect just enough light to show their full depth, especially on accent walls and trim. For color coordination, Astronomical pairs beautifully with red tones for bold complementary contrast, or with neighboring blue and teal hues for a harmonious, flowing palette. Its neutral undertone means trim and ceiling whites should lean neutral to avoid a jarring clash. If Behr is unavailable in your area, close cross-brand alternatives exist from Benjamin Moore, RAL, Dunn-Edwards and others. In terms of mood and atmosphere, Astronomical projects a confident, tailored sophistication associated with classic nautical and Art Deco aesthetics.
