Gradient color generation refers to the process of creating a smooth transition between two or more colors. This is often used in graphic design, web development, and digital art. The technique involves blending colors in a way that creates a smooth and seamless transition from one color to another. There are various algorithms and tools available to generate gradients, such as linear gradients, radial gradients, and conic gradients. These gradients can be applied to images, backgrounds, and other visual elements to add depth and visual interest.
