What would happen if a fully vaccinated individual were to contract coronavirus? Would it just feel like a light cold for them or would they literally not get sick at all?

The purpose of a vaccine is to prepare the adaptive immune system for an invasion by a pathogen, so that when it arrives it is immediately recognized and destroyed. Symptoms are a result of tissue damage when pathogens destroy host cells far beyond initial invasion. 

If you receive a low load long enough after you have been vaccinated you should experience nothing. A high load or frequent exposures will saturate your immunity and take effect to the extent that such a load would had you not been vaccinated. 

If you are exposed within a short window after one of your vaccinations, your adaptive immune system will be saturated and you will likely be more sick than you would have been had you not gotten the jab. 

Hope this clears things up.
