highlight duplicated items in two columns contains digits, symbols, letters and spaces

hi

I have many items are repeated between two columns A,B what I want highlighted the duplicated data between tow columns

if the items are duplicated in the same column or in another column with all the same spaces not different in spaces should highlighted by blue color and if the items the same elements but the different in spaces then should highlighted by green color the items contains letters ,digits and symbols if can do that without loop it will be a great
I put the result in second sheet

Some are duplicated with the same spaces and also with different spaces. How do you decide in that case which ones should be blue and which ones should be green? See "khalid omar" for the example. You have shown some blue and some green, but I can't tell your algorithm.

khalid omar in A12 and B12 are exactly the same (same spaces) as khalid omar in B4. Why is the one in B4 green instead of blue? They should all be blue.
