The book investigates the use of colour in art through artistic movements and research that stand apart from canonical histories on colour and abstraction, with multiple accounts relating to memory, politics, spirituality, storytelling, psychology and synesthesia By analysing the different colour theories that gradually took shape in the turbulent socio-political context that characterised the 20th century, Emotions of Color in Art reflects on a perspective that considers light, its vibrations and the world of emotions, while challenging the standardisation of the use of colour in the modern age (synthetic colours) and the digital era (RGB colours offered by various online palettes), a levelling that considerably reduces our ability to distinguish colours in the real world.
