Ammonite (LRV 69) reflects noticeably more light than Luau Green (LRV 29), a difference of 39 points that becomes especially apparent in rooms with limited natural light. Both lean warm, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 46.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

Ammonite vs Luau Green in Real Spaces
2 real rooms side by side. Seeing Ammonite and Luau Green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. The LRV gap is large enough that Ammonite will make the room feel meaningfully brighter than Luau Green would.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Ammonite reflects noticeably more light off the walls, making the space read more open than Luau Green.

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.
