Set unique class ID for every top menu link/sub-link (categorie)

[Saras B.]

Hello there,

 

I'm looking for a way to put unique classes for every top menu link(by categories id, cms id), to be able to change font color for categories trough css. I've handled with module blockcategories, but now i can't find information where to make changes and what changes to do to make it in blocktopmenu. Any help would be perfect, thank you. I'm adding image what i want to do if my explanation isn't good enough. :-)
