Aqueduct vs Little Blue Box
Both from Sherwin-Williams's palette. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Aqueduct (LRV 59) reflects noticeably more light than Little Blue Box (LRV 49), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 6.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Aqueduct vs Little Blue Box in Real Spaces

Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that Aqueduct will make the room feel meaningfully brighter than Little Blue Box would.

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.
