There is a color sequence as the dye is released from henna. About
12-24 hours after you mix your henna paste at 70F, you get a dark dye
release that's ready to bind with your skin. (Burgundy, coffee,
chocolate, red, depends on the batch) This stays at peak to about 24
hours after mixing paste. Then, the color of the stain slowly
degrades. I've been told that this is because hennotannic acid is a
dimer, and it's reactivity decreases over time. In any case, the
browns and reds slowly degrade to wuss orange.
When your paste is exposed to air, heat and light, this sequence
proceeds more quickly. When your paste is kept lightproof, airtight,
and cold, the sequence slows.
Put your nicely sealed cones next to the popsicles in the freezer!
