Watercolour painting is a technique that uses pigments suspended in a water-based solution. The transparent nature of watercolour allows for subtle layering and blending of colours, creating delicate and ethereal effects. It's often used to create landscapes, portraits, and still-life paintings. Watercolour paintings are known for their luminous quality and the way the light shines through the layers of paint.
