Is human blood ever any color other than red?

no

Explanation:

Human blood is red because of the protein hemoglobin. Hemoglobin contains a red-coloured compound called heme that’s important for carrying oxygen through your bloodstream

Sometimes blood can look blue through our skin, but its never blue. the reason we see blue is because blue light doesn't go as deep into kin as red. If the blood vessel is  deep, your eyes see more blue than red  light due to the blood’s absorption of red wavelengths.
