Setting color in objects

[Lukideluki]

I am doing a system to transform a DXF in txt code and be able to get the txt code and reverse, creating a DXF.

I am havving trouble with seting the color, because a get the color in Hexdecimal but i cant put it again, because just found a index method, by the code bellow:

msp.add_lwpolyline(line_mod, dxfattribs={'color': 1}) # add a LINE

there is another way to get and set in the add_lwpolyline the same hex that i get? I get couple of coordiantes and draw each object by a .add_lwpolyline
