Armstrong Caribou (ST294) is the warmer of the two darkest Earthen colors. It matches Taimen's 20-24% light reflectance, so the choice between them is about hue: Caribou appears as a warm taupe-brown in Armstrong's swatch, while Taimen leans gray.
Moisture tests on concrete have limits worth knowing before you buy. Relative humidity and calcium chloride results describe the slab only on the day it's tested and can't predict long-term moisture, and calcium chloride tests aren't valid on lightweight concrete, leveling compounds, or gypsum underlayments. Any area over the adhesive's limit has to dry further or get a moisture remediation system, and a third-party system's performance is that manufacturer's responsibility, not Armstrong's.
Finish: Diamond 10 Technology
Installation and warranty: Full-spread glue-down. The 30-year commercial limited warranty requires a recommended Armstrong adhesive, such as S-995 or S-1000, installed according to Armstrong's instructions.
