According to Kant intuitions without concepts are blind. I'm not sure I understand this but suppose the color red is an intuition and the awareness of the color as red or a more rudimentary awareness of the color red is the the concept. Couldn't it be argued that Kant is wrong because without a rudimentary awareness of the color red there would no red at all? Or was that Kants point? It seems to me that the "concept" of red is a precondition of red as much as the intuition and that Kant seems to suppose that they are at least theoretically seperable.
