Moody Blue vs Uncertain Gray
Both from Sherwin-Williams's palette. Hue-wise, Moody Blue belongs to the blue-grey family and Uncertain Gray to the grey family. Uncertain Gray (LRV 43) reflects noticeably more light than Moody Blue (LRV 26), a difference of 16 points that becomes especially apparent in rooms with limited natural light. Moody Blue runs cool while Uncertain Gray is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 14.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Moody Blue vs Uncertain Gray in Real Spaces
3 real rooms side by side. Seeing Moody Blue and Uncertain Gray in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Uncertain Gray reflects noticeably more light off the walls, making the space read more open than Moody Blue.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Uncertain Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Uncertain Gray reflects noticeably more light off the walls, making the space read more open than Moody Blue.
