Which side of a surgical mask should be outside and inside?

My friend says the blue-side should be outside but I think the white should be outside. I tried to google for the answer but only end up with more confusions.

Different articles say different things: One says the colored side always faces out while other says not to follow by the color and not all surgical masks have different colors on the two sides, some may have white on both sides or green, pale yellow etc.
