Hi everyone, I just wanted to explain exactly what changes were made so there is no confusion:
Previously, the four white colors were set using hue and saturation. This created a problem since colors ended up being different on different devices/brands due to hardware limitations, color conversions etc. For example, OSRAMs sometimes exhibited a greenish tint, some bulbs were almost cyan and some bulbs were ok.
In order to solve this and create a good experience for all different bulbs and versions, we changed the white colors to be set using color temperature instead. This means that if you put a LIFX bulb, an OSRAM bulb and a Hue bulb in the same room, their final shade should be close to identical.
Now if a light that does not support color temperature is used, it default to a hue/saturation value that is as close to the temperature as possible (calibrated against 2nd gen color Hue bulb). Again, since hue/sat is used this might not be perfect for all different devices out there.
The color temperatures used are:
Soft white (Default) - 2700k
White (Concentrate) - 4500k
Daylight (Energize) - 6500k
Warm White (Relax) - 3000k
For example, soft white at 2700k is very common when you by LED lights with a fixed color temperature.
Please provide feedback on devices that are way of what you expect, or if you believe the color temperature are not correct.
