how to copy a spreadsheet and retain the exact row colors

I'm trying to learn how to sort a spreadsheet (stock market data) by
individual columns (ie: dividends, EPS, etc...). As I first step I made a
copy of the spreadsheet and pasted it into a new spreadsheet.

The original one had different colored rows...first two rows white, next
three rows gray, next two rows white, next three rows gray, and so on. But
the copy I made has different row colors and some are too dark to read.

How can I make the copy or duplicate spreadsheet with the same original
colors?

Siva, I've tried the copy and paste three different ways but the result is the same. I tried copy/paste, copy/special paste, and insert copied cells. I tried selecting the cells from the topmost left cell, and also from inside the data area. I tried turning off freeze panes, and with freeze panes on. Always the same result, although on time the column width was greater than the original.

mehmetcik, I tried that but the problem remains.

If I knew how to, I would manually change the colors of the rows that are too dark. Where would I look to find how the creator of this spreadsheet set up the row colors? I don't know how to use the conditional formula that popipipo provided above, but there must be a repository of these formulas somewhere...
