Coverage result comes in grey colour

Why does the coverage graph of the coverage browser in specma come in grey colour instead of green? Is it because the number of ranges defined for an coverage item is large, if then what is the maximum number of ranges that can be defined so that the coverage result comes in green colour?

It would help if you shared an example of the coverage definition that's causing your problem...
Usually items are grey if they are deemed to be ungradeable, i.e. too many different values in a single bin, as you suggested in your question.
If you look in the Specman docs for "ungradeable items", you'll find a bunch of useful info: http://sourcelink.cadence.com/docs/files/Release_Info/Docs/sn_usage/sn_usage8.2/sn_usage.pdf
