I have very red palms and fingers, with white or skin color blotches, as well as the bottom of my feet are red. However my hands and feet are almost always cold. The closest explnation from internet searching was Palmar erythema, as suggest in the above post.
Palmar erythema can be a feature of chronic liver disease, pregnancy, thyrotoxicosis, rheumatoid arthritis, polycythaemia and rarely chronic febrile diseases, chronic leukaemia, or shoulder-hand syndrome.
Palmar erythema may also be the result of dermatoses such as eczema or psoriasis. It may also be a normal finding.
It has been attributed to high oestrogen levels."
If the redness is associated with peripheral change, that suggests a vascular etiology. Various studies like an ultrasound, or a physical exam to evaluate the peripheral pulses can be considered
It could be palmar erythema or raynauds disease. See link below about palmar erythema.
