Hello!

I have a .tif image I wish to add to ArcGIS using it's original colors, but when I add it (via Add Data) they change. Something to do with the bands I guess? How do you get the original colors?

See attachment for example.

Thanks!

It can be that it's using indexed color, or CMYK. If that's the case, convert it to RGB before importing in ArcGIS.

Ok, thanks!

To elaborate, TIFF is a vast specification. It’s very easy to write a program to write out a TIFF file. It’s practically impossible to write a program that reads every TIFF variant because the TIFF specification allows so many things, including some customization in the format. When you run into a problematic TIFF, read it into a mainstream program that can read it properly. Make some minor change to it (particularly, fix the color space to something normal and common and modern, if it’s not already.) Then write it out again.

Good luck.

Definately looks like it is something with the bands. Also note that ArcGIS by default applies a stretch to any raster images added, but that wouldn't look like this...

Most likely it is indexed, then you can adjust the colors/classes in the symbology, or you can convert it to RGB using e.g. Photoshop first.

This happened to me but when i was clipping a raster to a vectors boundary. I just messed about with the bands until it was more similar to how it was before the clipping. Would be good to know a better way though. Will forward this to Esri
