Color control using card_light in Lovelace Minimalist

Hi,
I just started using UI Lovelace Minimalist and have some Hue and Wiz lights which are RGBW tunable and dimmable.
I can change the brightness using the slider but cannot figure out how to change the color of the lights via the dasboard.
It shows the color of the light when changed via app as seen in the image.

Thanks in advance,
Parth


This is my code:

- type: "vertical-stack"
        cards:
          - type: horizontal-stack
            cards:
              - type: "custom:button-card"
                template: card_light
                entity: light.hue_spot_light
                variables:
