Dutch Tile Blue vs Halcyon Green
Both from Sherwin-Williams's palette. Dutch Tile Blue reads as blue-grey, while Halcyon Green reads as green-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (39 vs 38), so they'll read as similarly Medium in most lighting conditions. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 4.5 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 7 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Dutch Tile Blue vs Halcyon Green in Real Spaces
7 real rooms side by side. Dutch Tile Blue and Halcyon Green 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
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. The distinction reads clearly at room scale, making the choice between them concrete.
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. The distinction reads clearly at room scale, making the choice between them concrete.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.
