Gulf Stream vs Ammonite
Where Gulf Stream belongs to Benjamin Moore's range, Ammonite is a Farrow & Ball color. Hue-wise, Gulf Stream belongs to the blue family and Ammonite to the beige-greige family. Ammonite (LRV 69) reflects noticeably more light than Gulf Stream (LRV 39), a difference of 30 points that becomes especially apparent in rooms with limited natural light. Gulf Stream runs blue while Ammonite is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 32.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
