Foncé vs. sombre vs. obscur
The French words sombre, foncé, and obscur all translate to dark in English, but they are not interchangeable. Each word carries specific nuances related to color, light, mood, and clarity.

Summary
In summary, use foncé for shades of color (e.g., dark blue). Use sombre for a lack of light or a gloomy feeling (e.g., a dark room, a dark mood). Use obscur for a total absence of light or for something that is unclear and difficult to understand (e.g., a pitch-dark night, an obscure reason).
