My hands turn orange when im in the cold, what could this be?

Less circulation?: Raynaud's phenomenon is a symptom caused by constriction of small blood vessels, usually in the fingers and toes, leading to a lack of nutrients and oxygen going to the fingers and toes. Raynaud's phenomenon can be due to auto-immune disorders, hormonal imbalances, medication effects, etc... A primary care, endocrinology, or rheumatology doctor can look for possible causes of the hand symptoms.

Cold exposure: Fingers often turn colors when exposed to cold. The commonest pattern is white to red to blue. Transient color changes are due to reflex vasospasm which is constriction of small blood vessels followed by eventual dilatation. Raynaud's phenomenon usually occurs in some of the fingers and is mostly not serious but can be seen in various pathological conditions like autoimmune disorders? See your MD
