Raster colors not loading consistently #82

What is the bug or the crash?

Output from Analysis routines do not consistently load the correct color tables. Typical error warnings seem to be: "2022-03-22T10:46:13 CRITICAL ERROR 6: C:\Users\davee\AppData\Local\Temp\processing_pVfCXl\2a143c83a76741c4953606acf6b98cdf\accumulation.tif, band 1: SetColorTable() only supported for Byte or UInt16 bands in TIFF format." and

2022-03-22T10:46:13 CRITICAL WARNING: Too many values, color table cut to 65535 entries

I don't these are related, but they seem to be what show up. I say that because in back-to-back runs, the first run (with all18 possible pollutant output raster) only 1 raster was colored, in the second one all were colored correctly.

Steps to reproduce the issue

Run Pollutant analysis. See if all rasters get consistent (non-QGIS gray) color ramps. Try it again. It seems arbitrary.

Screenshots and Attachements

Correct colors mapping, all the same nutrients get the same color ramp, i.e., all Lead rasters are red, so only one of each is shown:

Correct_colors

No colors loaded, default gray colors:

Additional context

We've talked about this, but I don't think it is documented as an issue.

These two issues might not be caused by the same underlying function/class because Dave got some outputs that have colors but no units.
