The material color manager allows you to search the material color library when working with simple materials and linked complex materials on the material or product BOM. Whether or not the material color manager is available depends on the color control mode of the material.

You can only use the material color manager for those simple or linked complex materials that are assigned the color control mode of Existing Only or Existing (Allow Add). Press CTRL + ALT and then left click in the Color column for the material for which you want to use the material color manager. The Material Color Manager window opens.
