The goal with these moody color schemes is to establish the second act of the tale as a dark and foreboding chapter in the protagonist's story.
The quick digital sketches are sufficient to show scene composition and the color grading, but they also emphasize the ever present bright sparks of light, be it flame, flashlights or gunfire, that come to symbolize a constant threat.
Emphasis on color yet again, and using complimentary colors to heighten the power of the fire.
The first act is light and bright, indicative of a more pastoral time in the protagonist's life as a child.
This is the transition from the second to third act seeking to emphasize the returning light and the "dawning" of a new act.
The third act is a redemptive tale, largely conversational, storyboards need only bare essentials and sight lines, character placement, etc.

Indie Film Storyboarding

Rough film storyboard panels from various stages of scripting. Some explore color, some stage a scene, others are simple roughts to place actors.
