How is the color of an image visible in the corners of a linear gradient?

edit

The color of an image is typically not visible in the corners of a linear gradient. The gradient is a gradual transition between two or more colors, and the colors blend together smoothly. If an image is used as the background of the gradient, the colors of the image may be visible at certain points along the gradient, but not necessarily in the corners specifically. The appearance of the gradient and any image used in it can also depend on the precise settings of the gradient, such as the angle and position of the gradient.
