Option 1: Color Range Selection

Option 1 | Color Range Selection

Color range selection works best for pieces that are graphic and have only a few clear colors.

Select and convert a color to a Spot Channel
  • Select your first color range:
    • Menu Bar > Select > Color range…
  • Sample one of your colors using the eyedropper tool.
  • Use the Fuzziness slider to select more or fewer pixels. The white areas are the pixels selected. 
  • Click OK
  • With selected pixels loaded, go to the Channels menu panel. 
  • Select “New Spot Channel….” from the drop-down menu. 
  • Use the eyedropper to select your desired spot color from the Riso swatches panel.
  • Click OK

Your new Spot Channel will show up with your selected area as a mask. 

Repeat for every color. 

Make sure your composite channel is selected.

Change your mode to Multi-channel 
  • Menu Bar > Image > Mode > Multichannel
  • Delete all non-spot channels

If Option 1 color conversion works for you, skip ahead to Additional Optional Adjustments.
