Complex chain's color

Hi,

I have a model with one complex chain. /cfs-file/__key/communityserver-discussions-components-files/273/complex_5F00_chain.dgn

The color on complex chain's node is white, and the color on its curve segments are orange, and the curve displays as orange on CONNECT.

My question is that

(1) Is complex chain's color decided by its curve segments' color? Is it possible the curve segments have different color?

(2) Are there any flags to decide the display color (complex chain's or curve segment's)?
