Editing the Tracing Options
After choosing a starting preset to trace the image, you can then either accept the tracing results or adjust the tracing options to better suit your tracing needs.
- In the Image Trace panel, choose Tracing Result with Outlines from the View menu (see Figure 6).
- Choose Tracing Result from the View menu.
- Press and hold the Eye icon to the right of the View menu in the Image Trace panel to view the original image on the artboard. Release the mouse button to return to the tracing results (see Figure 7).
- Drag the Color slider to the left to decrease the number of colors in the Image Tracing object (see Figure 8).
- From the Palette menu in the Image Trace panel, choose Limited. Change the Colors value to 4 by dragging the slider (see Figure 9). After viewing the result, change the number colors to 16 or so.
Showing the outlines can be helpful for seeing how many vector shapes will be created when you trace.

Figure 8 Decrease the number of colors
If you look at the bottom of the Image Trace panel, you see a listing of the total number of paths, points, and colors. Notice that the number of colors listed there doesn’t match the number of colors listed in the Colors value (the slider). The Colors value refers to the color accuracy in percent of color. Less accurate means fewer colors (typically) and not depicting the color of the image as accurately.
Figure 9 Limiting the number of colors in the tracing result
The Limited option limits the number of colors in the Image Tracing object to 30 by default. You can adjust the Colors value (the slider) or type a number into the field to the right directly to edit the number of colors. This value allows you to choose the actual number of colors in the object, rather than a percentage.
