Color Method

Colors Methods are defined with the following settings:

kByLayer       0xC0            Color is specified by the layer object on which the object resides.
kByBlock       0xC1            Color is specified by the block reference color.
kByColor       0xC2            Color is specified by an RGB value.
kByACI         0xC3            Color is specified by an index (ACI) of a color palette.
kByPen         0xC4            Color is specified by an index of a pen color table.
kForeground    0xC5            Color is the same as the foreground color.
kByDgnIndex    0xC7            Color is specified by an index of a .dgn color table.
kNone          0xC8            Color is absent (object is clear).

NOTE: In LinkList2020, we do an And with 0x0F to just get the 0 to 8 and not the 0xCn portion. So LinkList2020 will write out “3” instead of “0xC3 for Color Index.
