.GRD File Association 2

File created by Photoshop, an image editing program; contains a gradient, or multi-color fill, in which colors incrementally change into other colors; commonly applied to drawing objects or tiled in background patterns; used to store and share gradients.

More Information

Gradients are designed to repeat colors even when the gradient space increases in size. Therefore, gradients can smoothly fill drawn objects or backgrounds without abrupt visual edges. They may use linear, radial, reflected, or angle formats.
