Get Line Style color

Revit
1

Hello!
I’m very new to the Revit API. I am trying to get the color of line styles. It seems like something changed in R22 where the python script I used doesn’t work anymore. “i.LineColor” still works, but returns a System Object, not sure how to get the Red, Blue and Green values. I commented out the original line in the script below. Can anyone help? I would also greatly value some instruction on how to figure out how to find this information in the API.

Thanks!

@achiHXDF8 Works fine for me in 2022 if you keep the original line as is.

Wow, that’s so strange, I wonder why it won’t work for me. :frowning:
