I think colour theory is really interesting. Like how and why colours affect the perception of a room and what colours do when you put them together. Such as the thing with warm and cold colours. Broken down illustratively, the warmth of a colour is associated its redness and yellowness while the coolness has to do with the blue- and greenness. Like hot fire and cool ice! That’s the simplest part, though it has a grey area; like the lukewarm beige borderline cases (I have btw finally settled for a beige paint hue!). Furthermore, the “coldness” of a colour tends to increase with the whiteness/lightness, while the hottest colors are fairly strong. And they affect room space as well: warm colours seem to invite us whereas cold ones distance, they have a depth effect. Anyhow, how you perceive a colour is always determined by its surroundings (and of course its gloss and texture etc): A colour is perceived as warm or cold on the basis of how it relates to the surrounding colours. This interaction can for example cause a red-violet hue to appear warmer if it is placed next to a cold colour, such as blue, or colder if it is placed next to a warm colour, such as orange. The greater the contrariety the greater the effect. Since carrot-orange is such a trendy colour right now, I think these temperature-balanced interiors make the perfectest point.
