Can't set color on Shelly duo, what am I doing wrong?

I’m using the Shelly integration:

And this is the entity:

I have tried various ways to set any color but nothing seems to work:

service: light.turn_on
target:
  entity_id: light.matildas_lampa
data:
  hs_color:
    - 200
    - 70

Or

service: light.turn_on
target:
  entity_id: light.matildas_lampa
data:
  rgb_color:
    - 255
    - 100
    - 100

But if I set the brightness it responds.

What am I doing wrong with color?
