To add a color wash (or color overlay) to a layer using a Gradient Layer Style, simply select the layer and click the “Add a Layer Style” icon at the bottom of the Layers panel and select Gradient Overlay from the list. (Note: the Layer Style must be applied to a layer, not the Background, to turn the background into a layer, double click the word Background.) In the Layer Style dialog, in the Gradient Overlay area, set the Blend Mode to Color and choose a gradient preset by clicking on the small downward facing triangle to the right of the gradient or create your own (by clicking in the gradient area and using the Gradient Editor). The advantage of using a gradient Layer Style over a Gradient Layer, is that this “effect” can be saved as a style (by clicking the New Style button in the Layer Style dialog) and then applied to any other image with a single click (using the Styles panel).
