How to get color of line on CAD importInstance

[KM_Yotsuha]

I link a dwg file to revit:

all lines are yellow, but when I lookup GraphicStyle, it is Red.

in cad,the layer's default color is red, and line instance's color is yellow.

the color of graphicStyle's Category seems to be the default color of layer,

so how to get the real color of line on CAD ImportInstance?
