The founder of abstraction Wassily Kandinsky advocated for a non-objective art that would not merely represent the world but turn inside the mind to express subjective experiences. Having learnt music before painting, the Russian painter and theorist aspired to transfer the unmediated power of sound to the creation of an emotional visuality. His expression ‘Each colour lives by its mysterious life’ constitutes one of the core strategies of his personal path in painting. Furthermore, his was a fundamental contribution to the perception of the art experience, closer to the spiritual than to intellectual engagement.
