Yes, but not in the full colour spectrum. Cows only have blue and yellow receptors in their eyes, not the red receptor, thus cannot see red, brown or pink-hued colours or objects. They are however, most attuned to bluish-purple and yellowish-green hues.
No. They can only see blue and yellow colour tones.

That's just like asking why us humans can see all colours of the rainbow. It's all down to the colour receptors in the eyes. Cows only have blue and yellow receptors, whereas humans have all three, which, unlike cows, enable us to see full-spectrum colours.
