Loading different CSS based on categories?

Hi, just wondering if anyone here has tried working with different CSS files based upon categories.

am working on a project now that encompasses different categories based on age groups. eg, Kid, Adult, Seniors. Needless to say, some vibrant colors will appeal more to kids then Adults.

other then creating seperate blogs. I think i can parse in the categories name dynamically but I’m not sure how this will work in archive mode. Anyone had the experience? Or is there’s a solution that I’ve miss whilst searching this forum?
