AutoCAD Color plotting black when pen setting is by color.

If you set the AutoCAD color to a True Color color it will plot by color no matter what the pen table.

Start layer menu > Double click on a layer color > Click on the True Color Tab > select a color with RGB or HL. RGB is easier to get standard AutoCAD colors.

True colors print as the color and can be used in situations when the coro should be printed in many situations.
