Hi Gene,
Are you talking about during the arua phase of a Migraine attack? Multi-colored lights, flashing lights, wavy lines, or even partial loss of vision may all be part of the second phase, aura, of a Migraine attack. Anatomy of a Migraine goes over each phase in detail.
Each person experiences aura a bit differently, and any new symptoms should always be reported to your doctor.
Good luck
Nancy
