The opening credits start off in the Locker-room of the Tyrell Corporation during the day with the words, "It's magnified and deeply revealed. Flecks of green and yellow in a field of milky blue. Icy filaments surround the undulating center," ("Blade Runner" p.1). Interpreting the author's choice of words, the 'field of milky blue' appears to be the sky itself. This description falls within the definition of Mimesis being that its uses descriptive tone to introduce a visual understanding of a scene. While it also fits within the parameters of Diegesis based on telling the reader in the beginning where they are, it uses more of Mimesis.
The next paragraph deals more so with verbal choices that give a better sense of the physical environment which the story is taking place. While there is a continued mention of color, there is also an addition of 'hard' words to describe the items within the scene. Such as, "The eye is brown in a tiny screen. On the metallic surface below, the words VOIGHT-KAMPFF are finely etched. There's a touch-light panel across the top and on the side of the screen, dial that registers fluctuations of the iris," ("Blade Runner" p.1). ...

It is common for people to have small particles of a different color that lie within their eye, so the 'flecks of green and yellow' would be the slight color imperfections within the eye itself.

The frequency of descriptive words plays into the author's narration intent. For a piece of work to be best comprehended and ultimately enjoyed, the narrative has to be at which a clearer picture is given of what it is that is trying to be said in the first place. The following two paragraphs are important to mention, especially in deciphering the intent of their usage, and the meaning of how the author may intend to have the story play out.
"The instrument is no bigger than a music box and sits
on a table between two men. The man talking is big,
looks like an over-stuffed kid. "LEON" it says on
his breast pocket. He's dressed in a warehouseman's
uniform and his pudgy hands are folded expectantly in
his lap. Despite the obvious heat, he looks very cool." &
"The man facing him is lean, hollow cheeked and dressed
in gray. Detached and efficient, he looks like a cop
