In JavaFx, Linear Colour Gradient is applied by an axis in which a colour changes gradually from one point to another point. We call this axis as Gradient Axis. If we draw a line perpendicular to a specific point in the linear gradient axis, all the pixels in the perpendicular axis represents same colour.
