MQTT Hub/Gateway

Hi guy’s. I’m totally new with this MQTT, but studied hard this weekend and managed to create a nice and working node-red MQTT dashboard. But I’m facing a problem with the lights. I want to control my mi-lights, but I’m only able to control the on/off, brightness and mode… I can’t figure out what I need for “topic” to control the color.

Ive tried (binnenring is the name of the light):

Works:
homie/homey-topic/binnenring/onoff/set : “true” / “false”
homie/homey-topic/binnenring/dim/set : 100
homie/homey-topic/binnenring/light-mode/set : “color” / “temperature”

Does not work:
homie/homey-topic/binnenring/color/hsv/set : “{“h”:295,“s”:0,“v”:0}”
homie/homey-topic/binnenring/color/h/set: 100
homie/homey-topic/binnenring/light-hue/set: 100
homie/homey-topic/binnenring/light_hue/set: 100
homie/homey-topic/binnenring/color/set: 0

When I watch the debug, and I change the lights hue, I see:

“”
(Maybe that’s some help?)
Anyway, can someone point out what the topic needs to be to adjust the color?
