Spring Thaw vs Blue Iris
Spring Thaw is a PPG color while Blue Iris comes from Sherwin-Williams. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. With LRVs of 71 and 73, they'll behave almost identically in terms of how much light they reflect back into a room. With a ΔE of 1.0, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Spring Thaw vs Blue Iris in Real Spaces
10 real rooms side by side. Spring Thaw and Blue Iris 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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Patio
Patio colors are seen under changing outdoor light throughout the day — morning, midday, and golden hour each reveal different qualities. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

5 simulated room previews — drag the slider on each to see Spring Thaw on one side and Blue Iris on the other.
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.
