Cultural Tip
In many Spanish‑speaking countries, talking about a "cielo oscuro" can also carry a figurative meaning, hinting at a gloomy or sad atmosphere. When you want to stress intensity, locals often add "bien" (e.g., "el cielo está bien oscuro"). Remember that "oscuro" must match the gender of the noun, so you would say "la noche está muy oscura" but never "el cielo está muy oscura."
