I don't think I've used this particular bulb (though one other that is pretty similar), and the "Advanced Zigbee RGBW Bulb" driver is probably your best bet. After switching drivers and saving, be sure to hit "Configure," wait a few seconds for the driver to run some tests, then try yourself. "Generic Zigbee RGBW Light" is also an option that might work--aside from the below.
With the bulb that I used, it did fine with color temperature but had some oddities with "Set Color." Specifically, I know it only reported color back in "xy" values rather than hue/saturation values. I can't recall if it even accepted "Set Color" commands with hue/saturation values (which is what Hubitat will send and is its native color model for reporting, too--though reports you might be able to live without if setting still works), but I wouldn't be surprised if that doesn't, either. I suggested the Advanced driver above because I believe these have some built-in conversion that can help with an xy-only situation like these bulbs.
I believe there is also a community driver for Ikea RGBW bulbs floating around that works around this by using custom commands to set colors from a pre-defined list. I'm not sure if it is still maintained or what exact models it works with. Here's one; there may be others: Tradfri LED RGB bulb - #67 by holand.ivar
That being said, they are not on the official compatible device list, and I suspect this is the reason. 
But it's possible you can make them work to some extent regardless--just not sure about the color piece.
