Tranquil Dawn vs Agreeable Gray
Where Tranquil Dawn belongs to Dulux's range, Agreeable Gray is a Sherwin-Williams color. Agreeable Gray (LRV 60) reflects noticeably more light than Tranquil Dawn (LRV 55), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Tranquil Dawn runs neutral while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 5.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
Tranquil Dawn vs Agreeable Gray Color Comparison
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.

Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Agreeable Gray reads slightly lighter here — a subtle but real difference in how open the space feels.

Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Agreeable Gray reads slightly lighter here — a subtle but real difference in how open the space feels.

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. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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. Agreeable Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
