My guess is those are just halogen bulbs, most likely found any any auto parts store like Auto Zone. Sylvania makes regular oem halogen bulbs, but they also make upgrade bulbs which are brighter/whiter for a higher price (ie; Cool Blue and Silverstar). The downside to those brighter/whiter bulbs is they burn at a higher temp and therefore their lifespans aren't as long as the oem bulbs. I used to install those brighter/whiter bulbs but I got tired of changing them when they burned out. Unfortunately they only lasted 1/2 the time of the oem bulbs. Sometimes they lasted only several months.
So yea, you can probably put whiter and bluer bulbs in there. Just be prepared to change them considerably a lot more often then the OEM bulbs.
