I stuck some random pieces of tissue tape onto a piece of heavy weight white card.
Using a brayer, I started with cobalt teal hue Decoart media acrylic paint.
For the next layer I added ultramarine blue.
Then primary magenta.
And finally a tiny amount of dioxazine purple.
And I added some marks using carbon black and titanium white, an old credit card and some bottle tops.
All paints are from the DecoArt media range.
