Gradient color in student's works refers to the use of a smooth transition between two or more colors to create a visual effect of blending. It is a technique often used in art, design, and digital media to convey depth, movement, or a sense of change. In student works, gradient colors can be seen in paintings, illustrations, graphic designs, and digital art, where the artist may use this technique to express their creative vision or to enhance the visual appeal of their work.
