A security document, such as a banknote, identity card and the like, having a substrate having a see-through window, with a first layer and a second layer being stacked in the region of the see-through window, - the first layer constituting a translucent, optically variable effect layer that at least partially covers the see-through window, - the second layer constituting an opaque, optically non-variable layer that is at least partially arranged in the see-through window and whose sub-region arranged in the see-through window is developed in the shape of a motif, - when viewed from the side of the first layer, a first piece of top-view information being perceptible in the form of the optically variable appearance of the first layer, when looked through, a piece of see-through information being perceptible that is at least codetermined by the sub-region of the second layer that lies in the see-through window and is developed in the shape of a motif, and when viewed from the side of the second layer, a second piece of top-view information being perceptible that is given by a combination of the optically non-variable second layer and the portion of the optically variable first layer that is visible in the see-through window, characterized in that - the second layer displays a fixed color impression in at least a sub-region and, with said sub-region, is coordinated with the optically variable first layer in such a way that the first layer and the sub-region of the second layer at least partially display substantially the same hue at a predetermined viewing angle. - the first layer constituting a translucent, optically variable effect layer that at least partially covers the see-through window, - the second layer constituting an opaque, optically non-variable layer that is at least partially arranged in the see-through window and whose sub-region arranged in the see-through window is developed in the shape of a motif, - when viewed from the side of the first layer, a first piece of top-view information being perceptible in the form of the optically variable appearance of the first layer, when looked through, a piece of see-through information being perceptible that is at least codetermined by the sub-region of the second layer that lies in the see-through window and is developed in the shape of a motif, and when viewed from the side of the second layer, a second piece of top-view information being perceptible that is given by a combination of the optically non-variable second layer and the portion of the optically variable first layer that is visible in the see-through window, characterized in that - the second layer displays a fixed color impression in at least a sub-region and, with said sub-region, is coordinated with the optically variable first layer in such a way that the first layer and the sub-region of the second layer at least partially display substantially the same hue at a predetermined viewing angle. - the second layer displays a fixed color impression in at least a sub-region and, with said sub-region, is coordinated with the optically variable first layer in such a way that the first layer and the sub-region of the second layer at least partially display substantially the same hue at a predetermined viewing angle.
