The blood vessels I would imagine you mean are the capillaries. These are the very thin blood vessels which run just under the skin and dilate in response to stress or increased body temperature to allow more blood to the surface. This causes flushing of the skin which gives it a reddish colour. This is more obvious on paler skins as they are more transparent than darker skins. The actual pigment in skin is a different thing all together and not supplied by blood vessels at all.
What else can I help you with?
Some people of European descent have a pinkish tone to their skin because of what?
The pinkish tone in some people of European descent is due to the presence of hemoglobin in the blood vessels near the skin's surface, which gives the skin a pinkish hue. Hemoglobin is a protein in red blood cells that carries oxygen to tissues and helps regulate skin color. The amount of hemoglobin near the skin's surface can vary depending on factors such as blood flow, blood vessel dilation, and skin thickness.

First, ALL blood vessels just under the skin look blue. Blood vessel color, or whether flatter or puffier, is NOT a pregnancy symptom. You might be confusing facts with a later pregnancy sign, when blood vessels in the breasts engorge (e.g. the vessels look bigger). Blood vessel color, size, or appearance anywhere that vessels are seen through the skin also has nothing to do with menstruation.
