Anyone able to set kelvin or color_temp to IKEA RGB bulbs?

I tried both with a Hue Bridge and a DeCONZ one and in neither cases I was able to set a kelvin or color_temp setting to my IKEA Tradfri RGB bulb.

May anyone report back their experiences with their own bridges/hubs (included the IKEA gateway maybe)?

What is the value of the supported_features attribute of these lights?

supported_features: 61

Ok, then it doesn’t support color_temp (or kelvin.) It does, however, support color (i.e., hs_color, rgb_color, xy_color, etc.), as well as transition, flash, effect and brightness.
