Changing Colour of Nested Block

Hi Is there a Autolisp to change Colour of a Nested block Retaining other properties?
If all elements in the nested Block have ByBlock color assigned, you can, but it would change the color of it in all insertions of the Block in which that one is nested. Or, you could give such a nested Block itself a ByBlock color assignment in its insertion in the definition of the host Block, in which case it would take on whatever color is assigned to the host Block, and that could be different in every insertion, as long as you're careful about the colors of other things that you might not want to be the same color as the nested one [if any].

The problem with this is it changes all the layers to 0. Is there a way to do without changing layer names
If I am correct [interpreting a combination of parts of Posts 1 & 3] that you want to change the color [only, and not the Layer] of all parts of a Block, including all parts of any nested Blocks, I think you should be able to do it by:
1) removing [or commenting out with a semicolon at the beginning] this line, which puts them on Layer 0:
(vla-put-layer obj "0"); to Layer 0
2) changing this line:
(vla-put-color obj 256); color ByLayer
to use the color you want instead:
(vla-put-color obj YourDesiredColor)
If you want them to be ByBlock color as suggested earlier, use 0 in place of YourDesiredColor.
Be aware that for nested Blocks, since it changes the color of pieces in the Block definition, it will change the color of every insertion of them, even any that are inserted on their own and not nested in other Blocks. So if you ever want the color to vary, use ByBlock instead of an explicit color.
