Colors are off with Sylvania Lightify Smart bulb

I’m coming from a Wink hub 2. I have 2 RGB lights that had nice yellow and red with Wink. The bulbs in HA are recognized as Osram RGB lights. They are connected directly to the HA hub, no bridge. This is the way I want it and the bridge support is going away anyway. I can adjust color and white temperatures. Most colors are fine, but yellow is too light whitish and washed out (doesn’t make a good summer bug lightł and red is a bit off, too. Any ideas how to configure them better?

Kind regards,
Nathan

What do you use to connect them? Deconz? Zha with any other stick?

Good point. My bad. Nortek combo stick and zha.
