Hi all, I'm a newbie to ArcGIS Pro, and most of the things I know I've either taught myself, read about online, or I remember from a bit of ArcMap training I had a few years ago. I have a hyper-specific question, and I'm struggling to find other community posts that even sort-of help. Apologies in advance if my jargon is wrong.
Basically, I have a feature class with a bunch of polygons (rooms within a building), and I am trying to display the symbology by the "Unit" that's assigned to that polygon. That much is simple. However, I have a pre-determined list of HEX color codes that are assigned to each unit, and I'd like to be able to use that list of color codes in Arc so that I can keep everything consistent. I can add the colors manually, but obviously that's super time consuming and doesn't help if I add more values and everything re-randomizes. I'd like to build an expression in Arcade that just automatically colors my map, as needed. I don't think Arc takes HEX color codes, so I can just convert to rgb, that's not a big issue. Below is my code that I've pieced together from other help forums, but it's not accomplishing what I need.
Like I mentioned before, I'm a complete newbie, and even newer to Arcade coding, so any and all help is appreciated. Thanks in advance!
Edit: I have ArcGIS Pro 2.7.0 if that helps!
