No, Dave. White is polychromatic — e.g. a mixture of frequencies in additive or reflected light.

Absolute black is the lack of reflected frequencies. Common black (what you actually see) is actually some frequencies in the darker regions being reflected — not a lack of all frequencies as in absolute black.
