Color table legend for GeoTIFF

Question

I have a single-band GeoTIFF whose entries are all integers. I'm creating this GeoTIFF using GDAL.

I would like to associate those integers with strings indicating what the integers mean so that the interpretation of the data can ride along with the data in a systematized way.

This is kind of like a color table.

Does GeoTIFF offer any mechanism for this? I'll be using this with GDAL and QGIS, but can do custom coding to make things work.

You want to add and show a Raster Attribute Table (RAT). There is a plugin https://plugins.qgis.org/plugins/RasterAttributeTable/ for that. There are some videos about how to use the plugin, for example https://www.youtube.com/watch?v=No9I3PHofss.
