A couple suggestions first:
(1) See if you can export/save your images as grayscale. These images are not all blue or green, respectively, and are just color-coded for display anyway.
(2) Try and avoid JPG, as it is a “lossy” format. Try PNG or TIFF
The main settings to note when using color images is in NamesAndTypes – be sure to choose the Image Type = Color (not grayscale). You didn’t attach your pipeline, so I can’t be sure, but that is likely your problem. (What Example Pipeline of ours are you referring to?)
See my attached pipeline. I used the “Combine” option in ColorToGray, which is not optimal since the scale changes because it averages the RGB channels, but it is the simplest to do until you can export grayscale images directly.
Hope that helps,
