Problem is, I don’t really know what to call the operation I need to do. The attachment shows a white space surrounded on three sides by different shades and texture of blue.
Is there a tool or process whereby I can fill that white space with gradients of the blues taken from the edges? I assume I would need to start with a layer to match the white space. If there is a tutorial I missed in going through the docs, I’d be glad to use it!
