Help for change element property lisp!

[norad]

Hi everyone i need some help for autolisp

 

I have many elements that have specific color (set to color 40,33,25,179... (not set to bylayer)) in my drawing

so i wish to find all elements that have above specific color, and change property of element to bylayer to see element with bylayer color

 

I found some Lisp but it changed all element's color to bylayer in drawing. it changed elements that i didn't want to changed to bylayer, so i asking for help here

 

is there any lisp can change element's color to bylayer ?

i wish lisp work only for elements that color set to color 40,33,25,179
