Photoshop has its version of selective color, shown in Figure 3-27, but it limits your selections to the sample colors they have included with the tool. The Coco plug-in (Figure 3-28) does not have preset colors, and the selection of color and the range of the adjustment are very liberalterrific for changing specific colors in an image without affecting any other colors in the image unless you want to. It is a bit pricey though.
I'm not a big user third-party plug-ins or filters because Photoshop alone enables me to do everything I need to. I do like one filter, though, and it reminds me of the Chromacom system. It's the Coco selective color correction tool plug-in. I have written to Adobe to ask them to incorporate this filter years ago, but it appears there have never been any changes to the Selective color correction tool (Figure 3-27).
