Colour has a direct impact on the brain, bright, bold, and strong colours arouse, pastels calm.
Sometimes colour is the image, sometimes colour is a supporting actor. We may choose to lift a colour out from the scene or suppress colour to make a point.
Bold colours – like a visual alarm clock.
Similar colours in pastel tones are more like a lullaby.
Using colour as the image.
Or colour can be a supporting actor.
We can emphasize a colour by lifting it out of a scene.
And we can suppress colours to emphasize a core subject.
