Two gradient color combinations

Quick answer：

A gradient color combination refers to the blending of two or more colors in a smooth transition. In design, these combinations are used to create visual interest and depth. There are various techniques to create gradient effects, such as linear gradients (moving from one color to another in a straight line) and radial gradients (colors expanding from a central point). The choice of colors and the gradient style can significantly impact the overall aesthetic of a design.
