Start Smart Light (Phillips Hue) at lower setting

I have a set of Phillips Hue bulbs that are really, really awesome, and can be turned down to a light level so low I can’t tell it apart from “off”. But when I use Sleep for Android to use them to “gently” wake me, they flip on to a admittedly dim red that still easily startles me awake when my face happens to be turned towards the bulbs. I don’t understand why Sleep doesn’t gently start the lux level at 0% and slowly increases it, instead of starting at what looks like about 40% of the maximum value.

Can this be either changed or be made a setting, please ?
