About this work

This painting shows wavy bands of bright pink, blue, green, and yellow stacked side by side. The lines twist and overlap, creating a sense of movement even though nothing is actually moving. The colors are flat and solid, with no shading or shadows. The artist used a soft, water-based paint called gouache, which lets colors blend smoothly. The title is just *Untitled*—no extra clues here. If you like this kind of eye-tricking pattern, look up gouache to see how it works.
