How to recolor a block inserted in a drawing?

A - answer If you have defined your block in a layer other than 0 or using entities with explicitly assigned colors (not BYLAYER or BYBLOCK), you will have problems to change the color of its references (insertions).

In such case use the BL0 (or the FIXBLOCK) LISP utility which redefines your block to layer 0. Both of these utilities can be downloaded from

You can also use the REFEDIT command or the newer SETBYLAYER (also for nested blocks).
