I have a program running fine on one device (laptop) but when trying to run the same code on another device (workstation), I have an error which does not occur on my laptop.
Setting colors in the .kv file works fine on my laptop but running on my workstation I have this error:

I am not sure why this error comes up, both devices have the same install of Kivy, same code etc. and setting colors using the words ("grey") works fine on the first machine. This error is specific to one line, but removing it throws the same error to another instance of setting the color.
Can anyone shed some light?
Edit: Minimal runable example
def build(self):
self.icon = local_directory + "\\LogoTransparent.png"
GUI = Builder.load_file(local_directory + "\\GUI.kv")
return GUI

Try adding:
#:import colormap kivy.utils.colormap
to your kv file, and change:
color: "grey"
to:
color: colormap["grey"]
without that change, I also get an error on that line. But my code continues to run (it just ignores that error).
