At LRV 65 vs 60, Nelson Blue will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. The tonal difference — Nelson Blue's green character against Agreeable Gray's warm — becomes most visible against white trim or in morning light. At ΔE 6.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nelson Blue vs Agreeable Gray in Real Spaces
3 real rooms side by side. Nelson Blue and Agreeable Gray 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.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Nelson Blue has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Nelson Blue gives the walls a little more lift.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Nelson Blue gives the walls a little more lift.

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.
