Color pencil gradient color matching with images refers to the technique of blending different shades of color pencils to create a smooth transition of colors in an image. This method is commonly used in art and design to add depth and realism to illustrations. It involves selecting a range of colors that gradually change from light to dark or vice versa, and carefully blending them together on the paper. This technique can enhance the visual appeal of a drawing by creating a sense of perspective and texture.
