A true albino lacks all pigmentation. There are various degrees of "lutinoism" where some but not all of the pigmentation is absent. You can, for example, get tiger barbs which are hypo-melanic, they lack dark pigment, thus have no stripes, but the red colouration is normal.
There is also a disorder called xanthism, which leads to an overall yellowish colouration. It is due to a build up of xanthine which is part of the waste processing reaction of adenosine monophosphate to uric acid, (it makes "pee" yellow). Fish that lack the final enzyme to reduce xanthine, show an abnormal yellow cast. Could be what you are seeing.
