To Change the Color Map of an Image

1. To display the Image Manager toolspace, click Raster menu Manage.
2. Click the Image Insertions view.
3. Click the image insertion for which you want to change the color map, right-click and choose Edit Color Map. Depending on image type, the applicable dialog box opens.
   Note: If you edit an existing palette color map that is used by several images in the drawing, the changes will affect all of the images. To affect only one image, you can assign the color map that is closest to what you want, then copy that color map and rename it.
4. Make changes as required.
