A gradient watercolor copy refers to a piece of art created by imitating the style and technique of watercolor painting, particularly focusing on the use of gradients to create depth and texture. Watercolor is a painting medium known for its translucent, flowing qualities and is often used to create delicate and soft images. A 'copy' in this context means that the artist is imitating an existing work, possibly a famous painting or a particular style of watercolor painting.
