That long painful howl you heard from the bottom of the planet today was moi.
Though for a much shorter period than usual, I did observe, arrange, and edit my warp colors over several days, during the day and at night, on sunny and cloudy days, with and without the lights on. So why did I have such a different picture in my head than what was right in front of me? I am speechless.
The irony is, if I set out to make a rainbow gradation warp, I doubt I would have come up with such a smooth transition.
