According to the homie3 specification it should just be 3 values h,s,v comma delimited to the color topic. They should be 0-255,0-100,0-100

color=200,70,80  
no spaces

I have not tried this on Homey but that’s how I’m using it on Hubitat with homie. I’ll try it later if I can find a colour bulb to add.

There is another variant when in RGB mode that supports the same 3 values RGB but each is 0-255 this time.

Im assuming this wasn’t Homey’ised’ as 0.0 to 1.0 float values… like dim level.
