----------------------------------------------------------------------------------

Full day in a south facing window for first week.

After the first week, started also giving an additional 5 or 6 hours in my grow tent each night. Lights in grow tent are professional MAXSISUN PB 1500 Full Spectrum which produce a white light. These exposure conditions are obviously much more brutal than museum conditions, but it does show us problematic colors quickly.

Test sheet is not behind UV museum glass and not fixed with any UV protective fixative.

Watercolor pencils were not put down wet, they were burnished to a heavy application, as were the regular colored pencils.

Paper is a vellum finish Bristol.
