New babies sometimes look blue, when all their blood vessels look the same colour as veins through the skin. What might cause this?

This because when they were in their mother womb they do not function any system ,they live due to support of their mother. So this is the reason

Your blood is always red, even when it is deoxygenated, so why do your veins look blue? They aren't actually blue, but there are reasons why veins look that way:

Skin absorbs blue light: Subcutaneous fat only allows blue light to penetrate skin all the way to veins, so this is the color that is reflected back. Less energetic, warmer colors are absorbed by skin before they can travel that far. Blood also absorbs light, so blood vesselsappear dark. Arteries have muscular walls, rather than thin walls like veins, but they likely would appear the same color if they were visible through the skin.
