Am working with 2 workbooks: book1.sheet1 and book2.sheet1. The task is
to search thru the usedrange in book1.sheet1 for cell with interior
colorIndex of 43 and apply to corresponding cell in book2.sheet2;
That means with cell of colorInedx 43 found, then identify and select
the corresponding value in the Column A. Then with that value turn to
Book2.sheet1 and Search thru column A for same value. Identify the cell
that corresponds to the one in book2 with color index 43 and apply
color index 56 to the cell.

both sheets contains same set data structure i.e same columns.
book1.sheet1 has more rows. Columns A arrangements are irregular.
Usedranges are not fixed. see illustrations below:
