Excel: Conditional Highlighting

I have a list of numbers, many of which are duplicates.

Is there a way to highlight the duplicates, with different colors for the different sets of unique numbers?

Thanks in advance. Example attached.

I would prefer that no VBA or array solutions be offered ... I'm a relative rookie in those areas, and would rather use a formula. Thx.

Excel already has built-in Conditional Formatting rules to highlight cells with duplicate values. There is also a built-in Conditioning Formatting rule to highlight cells with unique values.

But since you are requesting unique colors for all inputs, take a look at this website with helpful tips and tricks on finding duplicate values in Excel: http://www.excel-easy.com/examples/find-duplicates.html

I'm very familiar with the conditional formatting feature in Excel. What my question concerns is how to conditionally format duplicate values, with different colors highlighting matching sets of values, as per the spreadsheet example I attached. Thanks for the link, but it doesn't quite address my question.

If there are 500 matching sets, will you require 500 different colors?

Lol. I'd only need 20-25 colors. But theoretically, if it works for 25, it should work for 500.
