Replace Color Adjustment

If you want to use replace color on another part of the image just press OK after your first one and then bring up the image: adjustments: replace color again to do another color change (on the same layer).  Here I subtracted similar colors that were already selected by using the subtract eyedropper/turkey baster and adjusted the fuzziness to get a clearer selection this time off of his shirt.

But first I went back (cancelled) and reselected (clicked on the background in the replace color dialog box) to change the background color to pink.  Here I want to replace his shirt color instead of the background so I click on an area in his shirt. First look for areas that have extremely different colors (to make it easy). Click on the area you want to replace and then view the selection in the preview and use your eyedroppers and fuzziness to get the area as white as possible. 

Since I've got this shirt selected (and jeans) with white in the preview box, I've chosen a replacement color from the hue slider or color chooser. Go ahead and choose your new color.

It's best if the area you want to replace is the only color within the entire image so you don't see any other white areas (similar color selected) as part of the selection. But if there are outer pixels selected as shown that's ok because you can do something coming up here..If you want all kinds of advanced yet 'real world' commercial design training make sure you get my Madison Avenue Secrets DVDs.

Now go to your layer mask icon and click it. Remember that you are on a duplicate layer that you have now changed color pixels on. By creating a layer mask you can hide pixels from this layer to let the original layer and it's colors show through instead.

Now just grab a nice large brush from your brush tool palette or options bar and with black as the foreground color go ahead and start 'masking' on those areas of color that you want to hide to let the original show through instead.

Remember all you're doing is hiding this top layer's pixels. Yes you can use the eraser but it is permanent so I highly recommend hiding the pixels with the layer mask because you can always come back and make adjustments. 

Now we have the newspapers back to their original color, remaining ultimately unaffected by the color change now. Remember you can combine several Photoshop tools together like this to accomplish a goal.

Since his pants look supremely backflash 1980's, I've taken the brush tool and also masked/painted over the pants to let the original color show through -(much better) on this Photos.com image.  Press to view the rubylith (or at the bottom of the channels palette).  Layer masking is taught in depth in my training programs and covered also in my Madison Avenue Commercial Design DVD's.

Here is the original.

Final practice image. 

This method isn't perfect and doesn't work in all circumstances.  Note how because I didn't have a perfect selection from the dialog box how the original background starts to fade into the replacement color; this is probably because I didn't add those to the selection with the Add to eyedropper.  A safe bet.  Get the area you want white so it is selected in the preview box on a duplicate layer and then just hide the pixels anywhere you don't want the effect to be shown.  Once again, simpler backgrounds are easier.  Replace color only works on a regular layer where you can change the pixels and you can't do an adjustment layer of it.
