The top left rectangle should be filled with the blue linear gradient since the 'use' has a specified value defined in the 'defs' section. The top right rectangle is forestgreen since the 'use' has a computed value. The bottom left rectangle is also forestgreen since the fill is not inherited from the referenced element's original parent. The bottom right rectangle is filled with the orange radial gradient since the computed value is given by the CSS cascade.
