So then the answer is "Nem, nem piros, hanem vörös." :)
"Is the blood red?" is incorrect? I feel totally lost about when definite articles actually mean a definite article.

The "vörös" color name comes from the noun "vér", véres, vörös. So yes, a vér nem piros, hanem vörös. (És a magyar vér nem válik vízzé.)
Mine is blue
