The creation of an artwork with simultaneous contrast

The project described in this paper aims to illustrate the phenomenon of simultaneous contrast through a piece of artwork. The artwork is created with painted gomito pasta and Canson paper of different colours to exemplify the perception of small image elements (pixels) on different coloured backgrounds. Two colours, side by side, interact with one another and change our perception of the colours accordingly. The effect of this interaction is generally called simultaneous contrast. The colours in terms of physics and colorimetry are not altered; only human perception of them changes. Furthermore, the artwork also displays other phenomena; variations of simultaneous contrast, such as colour induction and colour assimilation. In real life, the colours we perceive generally do not remain the same when the background and viewing geometry changes, the proposed artwork provides a thought-provoking illustration of this to fact to the viewer.
