 When you open the image in photoshop click command j to duplicate three layers . select on the background then click the circle ball below the layer tool then press threshold to make the image black and white .
When u adjust the color select command e to merge . do this for all three images .
Turn off contiguous to select the all black with the wond tool.  Select sift and f5 to bring up a color tool and change it to foreground tool , make sure u select a color from the color panel before doing this. After that delete the white background for each layers .
