The Summer schedule for my Kessils starts out at zero intensity, zero color (all blue) at 6am, ramps to full intensity / full color at 11am, steady until 3pm, then ramps back down to 0/0 at 9pm. My Winter schedule is shifted an hour earlier (meaning no change for daylight savings). The all-blue is quite spectacular in the early morning and late evening, but I prefer to see real colors during the middle of the day.
Hope that helps.
