Colour can be subjective and each person has their own conception of what a good colour harmony is. The response to colour heavily depends on previous experiences and personal sentiments.
Chromatic Echoes is built through the same techniques as in printing, using gradients of the colours cyan, magenta and yellow. When the gradients are on top of each other and lit from behind new colours and hues are created by subtracting light being reflected through. The result is an experience where people can interact and explore their own conception of good colour harmony and compare it with others while also gaining an understanding of how colours and light work together.
