Can't remap to color 0 when saving DGN to DWG

Problem

When saving DGN to DWG, I am attempting to remap colors from the original setting to color 0.
The output DWG file converts colors to 7 color instead.

Solution

This is working as intended.
AutoCAD standard color index is from 1 through 255 and does not include 0. DWG 7 color has RGB values of 255, 255, 255 and is the standard color for white in DWG Workmode.
Use DWG 7 color instead of 0 color when converting DGN to DWG.


***Note - MicroStation's DGN color 0 also has RGB values of 255, 255, 255 which might cause some confusion
