Currently the desktop login screen icons are a single colour, unlike the nice icons we can import via .svg for the mobile login of RUN. Any reason we can’t see the coloured version in windows login??
I do believe that we set the color to black by default. I didn’t try it, but probably if you set the color field to null using the API to edit the TagoRUN settings, it would probably show the original icon color.
I added your suggestion as an issue to be fixed for our front-end team, and they should look on that in the next months.
