Gradient layer cannot embed other colors

Quick answer：

When working with gradient layers in graphic design software, it is important to understand that the gradient itself is a smooth transition between two or more colors. Typically, a gradient layer does not inherently support embedding other colors in the same way as individual color layers do. If you need to include additional colors in your design, you may need to create separate layers for these colors and use blending modes or layer masks to integrate them with the gradient layer. Techniques such as creating a custom gradient with the desired colors or using a clipping mask can also be effective.
