Colour at fullcalendar but not at node

Hi there,
I've been checking the issues, and maybe is because of my lack of technical background, but I haven't found an answer to my problem which is next:

I have events marked with taxonomy terms as types of events, each one with its colour, at the calendar colours are ok, but at the event node I only got the name of the tag without any colour, is it possible to get that, I will appreciate a lot if you advice me on how.

if you go to http://parles.upf.edu/ca/content/ultim-dia-de-classe-del-2n-trimestre
you will see where it says "Tipus d'esdeveniment: DC" (type of event) that DC is only in his link version without any colour.

Thanks in advance for your help
