So I bet we've all had that day where a customer will change color palettes a few times, and have us playing with shades of grey for an hour....argh! Well, I have this idea that I would like to use with all my Power Apps where I save the color in the SharePoint site in a list that the end user can change on demand! (Doesn't that sound enabling!? (smiles)
Here is the list I made (plus I made a connection to "ConfigColor" list in the Power App):
Note: dispite the display you see below for the second column - the internal name is just "RGB"

Then I created a Square Shape in my app, and in the Fill property I added this expression which is returning BLACK for some reason). LookUp(ConfigColor, "Tan" in "Title").RGB)
If I type the string in manually into the Fill property it's correctly color - but not via the filter. Can anyone help, is my idea a dud?
Thank you!
