An unusual question I am sure, but I recently had two blood samples taken in four days. The first my blood seemed watery and a light red colour, and my most recent blood sample seemed to be thick and dark red almost black in colour.
The first sample seems easily taken, but today it seemed to take much longer to get the same quantity of blood, and since this my arm is painful and achy.
The question is can anthing be told by the colour of blood? Is there anything I should be concerned about?

Sounds like you were dehydrated today, try drinking more next time.

Depending on from where the sample was drawn, yes, it is possible to get different colored blood samples. Venous blood is darker because of the carbon dioxide it is carrying. Freshly oxygenated blood is bright red and flows through arteries.
Discuss with your health professional, your concerns about the color and viscosity changes and the pain in your arm.

Sounds like we could make black pudding out of the last lot of blood they took. Don't worry..blood is lighter when oxygenated. your last blood sample sounds like it was all out of oxygen (on its way back to the lungs for a top up).

The color depended on if they took it from an artery or vein
Artery - bright red, fills quickly
Vein - Dark red, fills slowly
