to give a straight answer, (the english term) "white" originates as a colonial term and was coined by anglos in a society where the necessary distinction was white vs. mulatto vs. black. it originates as a practical distinction in colonial america and was never meant to be scientific.  racial science of the late 19th to early 20th century categorizes the major european races as nordic, alpine and mediterranean, obviously with gradients of admixture. all of these are "white", but the way "white" came to be used in america it defaults to nordic phenotype. core romanians belong to the alpine race, with some mediterranean admixture from the ancient colonies at the mouth of the danube and bessarabia.
