I have two rasters that have been cropped and masked. One with a colortable (test_ctb.tif), the other without (test_nctb.tif). For the NoData pixels, the one with colortable (test_ctb.tif) identifies its value as 0 while it should show NoData. When I switch to unique values, then both rasters show correctly NoData for that pixel. The color table works fine in ArcMap 10.8.2 though!
Solved! Go to Solution.

Hi,
You may need to modify the colortable of the raster with the incorrect NoData values in the "Colormap" pane > Edit "Colormap" > Check the "Use values" checkbox and enter the NoData value for the raster. This is to be the same value used by the other raster that has correct NoData values. Try these steps; it might solve the issue.
Thanks,
Omar
Hi Omar,
Thanks for the post! I do not see any "Use values" checkbox under Symbology for Colormap? And neither edit option for the Colormap? When I click file Properties > Raster Information NoData Value is 255 which is correct.
And I added that yellowish under the Mask to Nodata, so it correctly finds that NoData, but displays incorrectly its value.
