If you're in an area where bougainvilla in general grows really well, I'd say just don't worry about it as long as it looks healthy overall. I don't have any better advice than that because I have one that basically grows like a weed and has to be sheared back every couple of months. And yes, there are times when there's more color than at other times.
Maybe one of the other green thumbs out there can give you better information! Even after more than 10 years in a place with basically no winter (we have a rainy season, but it doesn't really get that much colder), I'm still not always sure what's going on. Some things never die back; just cycle year round (boug., daylilies, roses), others do (fruit trees, peonies, daffodils and so forth). So it can be really confusing. My fallback is just leaving most things alone; fertilizing when things yellow or look peaked; watering to get drought tolerant things established but then backing off.
Gotta go...dd can't decide whether she wants to eat a cracker or brush her teeth, but she wants me along for the ride.
