Colony Green vs Tranquil Dawn
Where Colony Green belongs to Benjamin Moore's range, Tranquil Dawn is a Dulux color. Colony Green reads as green, while Tranquil Dawn reads as green-grey — two distinct hue families, not close cousins. Colony Green (LRV 66) reflects noticeably more light than Tranquil Dawn (LRV 55), a difference of 11 points that becomes especially apparent in rooms with limited natural light. Colony Green runs green while Tranquil Dawn is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

5 simulated room previews — drag the slider on each to see Colony Green on one side and Tranquil Dawn on the other.
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.
