Carbon Copy runs green while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 42.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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 Tranquil Dawn will make the room feel meaningfully brighter than Carbon Copy 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.
