It depends on how you look at it (pun intended). If you are asking if you can see the blood or blood vessels in deep vessels through the skin, the answer is likely no. It depends on which vessels, how deep they are and how much subcutaneous tissue the person has.
If you are asking if the deep vessels help feed blood to the skin which adds to the color of skin, then the answer is yes (although not directly, if talking about large vessels instead of small arteries and capillaries that the deep arteries feed). What gives the skin of Caucasians its overall pinkish hue is the blood that fills the capillaries. According to Hole's Human Anatomy and Physiology 12th Edition p176 "Blood in the dermal [skin] vessels adds color to the skin."
If you are talking about the "optical illusion" that light can play on skin which makes the surface veins look blue, then no. The skin is not actually colored or discolored when you see that, you can just see the veins through the skin and subcutaneous tissues because the veins are not as deep as arteries. They look blue due to the properties of light shining on skin. The veins and blood are red, they only look blue through the skin due to the optical illusion. The myth about blood in arteries being red and blood in veins being blue is just not true. The additional myth that the blood in arteries turns red when the air hits it when bleeding due to oxygenation from that air, that, too is scientifically incorrect.
There is only a slight difference in color of the blood in arteries and veins, both are red. The blood in arteries is bright red, and the blood in veins is a darker red due to several factors, but mostly because the venous blood is carrying off wastes that add to the darker coloring of the blood in the veins.
If you are talking about the color differences between races and those with suntans, then, no. For the most part, melanin determines the color of your skin in those circumstances.
No, however, depending on how pale you are, it may give your skin a red hugh. Melanin gives the skin its color.
Melanin is produced by melanocytes which are a specialized skin cells.
The superficial blood vessels give color to the face.
yes it does
Melanin gives color to your skin and eyes.
Melanin. The amount and type of pigment in the iris of the eye gives the eye it's color.
Melanin is not the agent reponsible for coloring red blood cells. Melanin gives color to skin, parts of the eye, hair, the inner ear, the brain, and adrenal glands, though. The substance that makes the blood cells red is iron. It's actually a very pure form of 'rust'. Hemoglobin is also associated with red blood cell color.

Skin gets its color from melanin. The more melanin a person's skin has, the darker their skin will be.
