I'm always impressed when someone starts stretching the boundaries on creativity. Over the years I've always been interested in color theory and how it can be used as either a subtle or bold element in a composition.
@enezdez I didn't address one part of your later posts, " blue is to show the coldness of the moment". That made me think about how best to show winter cold. I little light reading found some guidance on the subject which put forth the idea that there are different types of winter days with different color palettes.
First up is a "True Winter" these are high contrast, bold and bright, from pure black to pure white, these days are when colors shine like jewels. Using a color palette that reflects that, bright reds like cherry & holly berry red, emerald green, cobalt blue, rich purples and stark black and white (or those of the same color families) all in high contrast, will make it pop.
Second is "Bright Winter", an even brighter version, except the colours have a little of Spring's lightness added to them maybe even bordering florescent. A color palette that brings in a little of spring, pinks, yellows, blues, greys more to the cool side will work well on these days.
The third type is "Cool Winter". Here you start losing some of the brightness of the first two, and picking up more darkness in the shadow. You'll start to see slightly deeper colouring than their brighter counterparts. A color palette of charcoal grey, deepest indigo, navy, burgundy, and very pale grey is better pale neutral than stark white.
Finally you have "Deep Winter" which can be deceptive in its hints of warmth, more toward the late autumn palette, but with cooler accents rather than golden. Here a color palette of things like darker reds and greens, navy blue, dark forest green, stone grey, pebble grey, (the darker shades leaning toward brown). Whites are usually missing.
