hitting error due to "unsupported color in the note"

[ariccb]

not sure exactly what's causing this - but I know that the note it's always notes that contain a variety of "title" sections in different "color" choices.
not sure which style is throwing the error but here it is:
i'm on the latest version A6X Chauvet 2.15.29
and using supernote-tool version Version: 0.5.0

returned non-zero exit status 1.
Error output: Traceback (most recent call last):
