I have scanned our old zoning maps that are printed on white paper with colored polygons representing the zoning classifications.  These were done in 1989 on a plotter. 

When I scan them at 75dpi in color as a .tif image, they come out exactly like they look on the hard copy.  When I georeference them, then use the Data Management-Raster-Raster Processing-Clip tool, the colors come out much darker and some of the polygons are black.  Any reason for this happening?  The .TIF files are 3 bands.  I uploaded my 2 files as jpeg, but they look exactly like the tiffs.
