I thought so far, in these lamps is RGBW (red-green-blue-white). Until my glass capsule a Hue-lamp is broken. The lamp was working to remove the glass remains continues, but now with directed light, more like a spot. It is noticeable that the lamp has three light colors: white, red, blue. It has three white, three red and one blue LED. However, the latter lights up only very weakly. The white LEDs are extremely bright and different from normal white LEDs is that they light up slightly greenish with dimming. I suspect, under the white phosphorus sit green LEDs instead of blue. Philips calls these lamps therefore "Extended Color Lights" to distinguish them from normal RGB lamps. You can not cover the entire color spectrum, but only the "sun colors" white, orange and red with it. Yellow, green and blue, there are only suggested as a pastel color. Apparently Philips sees the colors blue and green for lighting in the living area is of doubtful use to. For people who want to have these colors, Philips offers as an alternative the "Living Colors" series. However, these lamps are not a true RGB system, as it is known from other manufacturers.
