The phrase evokes a visual image of a scene taking place under a light-colored, often washed-out, expanse of the atmosphere. Such imagery can suggest a variety of conditions, from early morning or late evening light to overcast or hazy weather. For example, a figure walking on a beach might be described as existing in this environment.
The significance of such a description lies in its ability to establish mood and setting. It can communicate a sense of tranquility, isolation, or even foreboding, depending on the context. Historically, artists and writers have used similar descriptions to enhance the emotional impact of their work, grounding the narrative or artwork in a specific and evocative environmental condition. This type of atmospheric detail adds depth and realism.
