How does the Color.FromColorIndex work?

[ilovejingle]

attDef.Color = Color.FromColorIndex(ColorMethod.ByBlock, 1);

I found this code works for changing the entity's color. 

I know in AutoCAD we have 0 to 256 index colors where 0 should be byblock and 256 should be bylayer. but what the two parameters in this method actually mean?

With ColorMethod.ByBlock or ColorMethod.ByLayer the 2 parameter are redondants.

For indexed colors, you should ue: ColorMethod.ByAci.

Or simpler, use the Entity.ColorIndex property instaed of Entity.Color.
