Why is it that the flowers change color? I have a number of colors and I have noticed a nice yellow changes into pink, and sometimes orange. Also, the Picaso color changes from the two-tone to cream or light purple and sometimes almost green. A chocolate color has changed to red. Has anybody else experienced the same or have an explanation for what is happening? Regards, DEON ERASMUS PORT ELIZABETH.
