Merging Colors

After you posterize the image, you may want to get rid of some colors. For example, an area in the image which looked orange may become a mixture (or pattern) of yellow and red after posterization. In this case you can merge these two colors in order to get one solid color for the whole area.

1. From the list of colors in the dialog box, select the colors you want to merge together.

   Use Shift and Ctrl (command in Macintosh) to select multiple colors. The color you want to be the result of the Merge must be selected last. The result of the merge will be displayed in the lower-right corner of the dialog box.

2. Click Merge.

   All pixels in the image that have the selected color will be converted to the desired color.
