I am posting some reference from the animated film “The Secret of Kells”
These are color timing sheets used to show the palette that will be for a specific sequence. The emotion and tone of each sequence is influenced not only by story line and action but is also set by the color and light and shadow.
The opening sequence is one of mystery and cold logic. So the color timer chose a gray blue/gray green palette with complimentary desaturated yellow and magenta for accents.
Also notice how the artist has played with light and shadow and camera angle to set the mood.
The next sheet is a happy go lucky goose chase sequence. Notice the colors are much more vibrant and saturated. The lighting is outdoors and bright.
The next sheet is in red. Whenever Vikings are a part of the story the image becomes almost monochrome red and black. This is to show the danger the vikings pose to the monks.
A color timing sheet from a scene where Brendan the hero of the story is about to face a scary mythical monster. The color palette is a washed out gray green with red as highlights to signify the danger. Notice they didn’t go with the full red of the vikings. The gray green to me signifies an older danger, not so immediate like the vikings.
Finally I am posting some color sketches. You will notice that in some cases the details, techniques, style, (cartoony not cartoony) are not as important as the feelings and mood that the image evokes.
