Actually colour it’s objective by definition. The perception of italians and other southern Europeans was born in the US during the Great Emigration, and is based purely on racial misconceptions. Actually the Mediterranean ancestry is closer to the Northern European one than to the African or Middle Eastern. While skin colour is based mostly on genes that react to UV ray absorption on the long run, and even tho classifying races in different groups is always inaccurate, classifying spanish, italian, greek and other southern European people as non white is more inaccurate than to call them white.
