This digital artwork, part of the series The Flow, is available in colour both as in black and white. Oftentimes there is a significant shift in the meaning, by using colour or not. I regularly make multiple versions to see the effects of it. Since 2019 I work a lot with the program Procreate.
If we look at giving and receiving from the heart, then it will sometimes flow easily, but sometimes there are obstacles. The colours also show the dynamic between warm and cold.
