We will work on this skull design that one of our artists created recently, but didn't get the chance to clean it up yet.
STEP 1
Select the entire artwork. Click the "Recolor Artwork" button on the top buttons bar. It will show you the real number of colors used and you'll get an idea of how you can fix them.
STEP 2
First, open the Swatches palette (Window > Swatches) and click the "New Color Group" button. This will create a palette of all the colors you used in your design.
STEP 3
Grab the Rectangle Tool (M) and draw a rectangle near your design.
STEP 4
With the rectangle selected, click the color in the created color group that you want to remove.
STEP 5
Grab the Magic Wand (Y), press Enter and set Tolerance value to "0". Then click the square. Now you should have selected every shape in your design that has that specific color.
STEP 6
From the Swatches palette (Window > Swatches), click the closest color tone from the created color group. Then click-drag the unwanted color onto the "Delete Swatch" button.
To show the colors you used, create more rectangles and color them with all the colors from the remaining color group. It's very helpful for someone to recolor it quick and easy.
