Replace a color in an image

In the Layers palette, select the layer containing the color you want to replace.

If you want to replace color in only a specific area in the image, use a selection tool to draw a selection marquee around the area you want to change. The selection marquee limits the changes to that area.

Choose Image > Adjustments > Replace Color. Arrange the Replace Color dialog box so that you can see as much of the image as possible.

In the Replace Color dialog box, make sure Selection is selected under the preview window.

In the image, click the color you want to change. The preview displays the areas that match the color you selected.

If you need to expand or refine the areas to be replaced, click the Add to Sample button  or the Subtract from Sample button , and then click another area in the image.

In the Replacement area of the Replace Color dialog box, click the Result color swatch.

In the Color Picker dialog box, locate the color range you want using the triangle sliders on the color spectrum bar, then click the desired replacement color in the color field. The color you select appears in the top half of the color swatch. The original color remains in the bottom half. Click OK. Photoshop displays the new color in the image.

If you need to replace additional colors, select the Add to Sample button , and then click the colors in the image.

When you are satisfied with the color replacement, click OK.
