How to set color of individual cell of a column through absl script

Hi

I would like to know how to set color of individual cell of a column through 'absl script'.

What data type can be used to store color in the Business Object.

I tried it though ruby scrip using calculation rule. I was able to do so. But ruby scrip does not work on HTML 5.So couldn't continue with the same.

Regards,

Vandita
