Deep Space Blue is a deep blue from Little Greene. As a premium paint, it’s a popular colour to seek out close matches and value-brand alternatives to.
Oxford Blue (Weathershield) by Dulux is the closest match from any other brand (close) — and it holds Deep Space Blue’s lightness, warmth and saturation alike. The closest value-tier option is Cowboy by Johnstone's (close), lighter (about 2 LRV points), slightly warmer and slightly softer. A warmer match reads warmer again in a south-facing room that gets direct sun. No other brand gets within a near-identical match of Deep Space Blue — it’s one of the more distinctive colours in the library, so expect a visible difference whichever you pick. LRV is estimated from each brand’s swatch, so order testers before committing.
