you can simply do that with conditional formatting:
select range A1:A10, open conditional formatting, new rule, use formula, and use this formula: =AND($A$1>0;A1>0), and format with the colour you want to apply to this range. But if you want to change the colour for this range based on cell values, you can do this only with a simple macro. Just tell us if you need more... Good luck!
You can take a look at the sample atached.
