How to slowly dim from color to white?

Configuration
1

Hi.
I have made a wake-up like setup based on this post.
It works, but it ends in a kind of medium bright whiteish-blue.
This is properbly because it use yx colors. I am not able to make it bright white myself by clicking the color-chart in GUI, bit if I click somwhere in the color temperature scaler it becomes white and a lot brighter

I use an automation similar to the example on the Lights documentation page:

automation:
- id: one
  alias: Turn on light to preset colour
  trigger:
    - platform: state
      entity_id: light.light_name
      to: 'on'
  action:
    - service: light.turn_on
      data:
        entity_id: light.light_name
        brightness_pct: 100
        kelvin: 4000
        transition: 5

If you are using an Ikea Tradfri bulb, be aware you will need to set up two separate actions, one that sets the colour, then one that sets the brightness.
