At ΔE 53.5, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.

Lullaby vs Sea Serpent in Real Spaces
2 real rooms side by side. Seeing Lullaby and Sea Serpent 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
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. Lullaby returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The LRV gap is large enough that Lullaby will make the room feel meaningfully brighter than Sea Serpent 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.
