Subject: Does coating a plant's leaves with mayonnaise affect the leaf's pigments?

I was testing transpiration on Coleus plants by coating the top and bottom 
of the leaves with mayonnaise along with other substances.  The pigments 
in the leaves of that plant changed color.  The yellow disappeared and the 
green part in the leaves grew darker after the mayonnaise was applied.

It was within about 6 hours that the leaves turned.  The light purple turned
almost to a black and the light green changed into a dark green.  I repeated it
with another plant, and the same thing happened.

Hi Jenny - It would help to know the time course of how/when
the pigments changed - was it a matter of days, a week, or more?
Cheers..
