Paint email a different color for each attribute

One of my attributes is priority, it is an enumeration with values from 1 to 3.  1 being the most important. I would like my email to be painted red if the enumeration is 1 for example.    Any ideas?

Which e-mail module are you using? If you're using one that allows you to work with templates, I would create a decision in the flow that retrieves the template based on your enum values, and then retrieve the template that has the correct colour for your enum value.
