The painting uses thermochromic pigments whose reactivity changes over time depending on the number of activations. This is intrinsically part of the concept of the painting, which by definition negotiates the state of things with the course of things, organicity and transformation. The viewer is confronted with an 'organic' process of matter that slowly changes due to its nature. It is up to him to decide whether to accept this change over time or to paint over it to reactivate it. Through this decision, the owner actively engages with the state of the artwork and time, formalising the relationship he has with the artwork.
