nah man,3300k would actually be yellow,yours are more around 4300-4500k,like every oem hids out there,wich are the brightess color range,if you go aftermarket replacement bulb,like 6000k,depending on the make,it could be bluish,or look oem but a bit more powerfull,like my 6000k bi-xenon helios,compared to my friends infinity g35x hids,mines are far more brighter...
dont forget that on the ms6(wich i guess youre talking about) the projectors lenses are a bit tinted,so you have the impression that the hids are not as crisp as they should be....
most of the companys are 4300k for oem hids,the color can change a bit with the type of headlamps,either projectors or reflectors.....
