Peek a Blue is a calming choice — works as both a whole-house neutral when lightened and a dramatic anchor when deepened to navy. At LRV 71 it reflects plenty of light, which makes it well-suited for north-facing rooms and smaller spaces that benefit from extra brightness. Skip it in low-light north-facing rooms unless you want a deliberately cool, cocooning effect, since blue can read chilly there.

Peek a Blue Technical Profile
What color is Behr Peek a Blue (T17-04)? It's a light cool blue — hex #C5E1E1, LRV 71. The closest cross-brand equivalent to Peek a Blue is Dutch Boy Delectable Aqua — a near-identical match on the wall, with Valspar Tropical Spray and Benjamin Moore Bird's Egg also close. With a Light Reflectance Value of 71, Peek a Blue reflects a generous amount of light, making it well-suited for north-facing rooms or smaller spaces that benefit from extra brightness. Pair it with cool whites like Chantilly Lace, walnut or rift-cut oak floors, and brushed nickel or polished chrome hardware. Brass accents add warmth for a layered look. At mid saturation, this color sits at a flexible mid-point — bold enough to anchor a room without dominating, and pairs cleanly with both crisp and creamy whites. Blues stay crisp under 4000K+ cool LEDs. Under 2700K warm bulbs they can read grayer or shift slightly purple — particularly true for mid-tone and saturated blues. At mid saturation the lighting shift is moderate but real — sample under both warm-bulb evening light and cool-daylight morning light before committing.
