Mild Blue vs North Star
Both from Sherwin-Williams's palette. Hue-wise, Mild Blue belongs to the blue family and North Star to the blue-grey family. Mild Blue (LRV 65) reflects noticeably more light than North Star (LRV 62), a difference of 3 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. At ΔE 3.0, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Mild Blue vs North Star in Real Spaces
2 real rooms side by side. Mild Blue and North Star are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Mild Blue reads slightly lighter here — a subtle but real difference in how open the space feels.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Mild Blue reads slightly lighter here — a subtle but real difference in how open the space feels.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
