Is it normal to see green veins on your hands?
Yep.Totally normal
Yes, visible greenish veins on your hands are usually normal. Thin skin, lighting, and how close the veins are to the surface can make them stand out.
Hand veins often show through because the skin there is relatively thin, and veins can look green or blue depending on lighting and your skin tone. They may also look more noticeable when your hands are warm or after exercise.
If the veins suddenly become much more prominent or you notice pain, swelling, redness, or warmth, get medical advice. Otherwise, visible green veins by themselves are usually just a normal bit of anatomy.
