Custom:slider-entity-row temperature words instead of numbers

I have a custom:slider-entity-row card setup up like this:

type: entities
entities:
  - light.spotjes
  - type: divider
  - type: 'custom:slider-entity-row'
    entity: light.spotjes
    name: helderheid
    hide_when_off: true
  - type: 'custom:slider-entity-row'
    entity: light.spotjes
    attribute: color_temp
    name: warmte
    step: 5
    hide_when_off: true

which is working fine, but instead of having a number behind the slider in the
attribute: color_temp
i would like to create a slider that goes from the words “cold” to “normal” to “warm”

is there any way to replace value XXX till XXY by words?

thanks,
Tom
