The information and video below show the new color dialog available in OpenRoads SignCAD 2023. 

The new Color dialog has the Standard Colors as well as any other color needed. The color formula and name are stored in the SGN file. The Standard Colors can be selected from the pick menu at the top of the Color dialog. Other colors can be selected using the color selector or by entering the RGB, HSL, or hexadecimal values directly in the Color dialog.
