The antonyms for the word "most sunlit" could be "cloudy," "shady," "gloomy," "dull," and "dark." Cloudy weather means that the sun is obstructed by clouds, so it cannot visually light up the environment as actively as it does during clear, sunlit weather. In a shady place or an area covered by a tree's canopy, the sun does not directly penetrate the foliage. So, the area remains slightly dim or shaded compared to an intensely sunlit area. Gloomy and dull refer to a type of overcast weather, where the sky is dark, and there is no direct sunlight. Similarly, dark places can't be well-lit by the sun at all.
