Can anyone provide me with some intuition about what might cause an error like this?
Argument of \XC@definec@lor has an extra }
I am unable to produce an MWE that demonstrates the error, as it occurs in a large document and when I extract the part that seems to be causing the error and compile it by itself it works as expected and does not produce the error.
I think that it is related to a TikZ picture I am trying to draw.
