How to add multiple gradients

Quick answer：

To add multiple gradients, you can use a technique called 'gradient overlay'. This involves creating multiple gradient layers on top of each other, each with its own gradient direction and color stops. Adjust the blending mode of each gradient layer to combine them artistically. For example, you can use 'overlay' or 'multiply' blending modes to create interesting effects. Software like Adobe Photoshop or Illustrator provides tools to create and modify gradients in this manner.
