Sky blue vs Blue Plate
Where Sky blue belongs to RAL Classic's range, Blue Plate is a Sherwin-Williams color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (19 vs 17), so they'll read as similarly Dark in most lighting conditions. The ΔE 5.1 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Sky blue vs Blue Plate in Real Spaces
2 real rooms side by side. Sky blue and Blue Plate 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.
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.

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.
