How to control digital white to achieve whole daylight

as we know,it is easily control the digital rgb to achieve different color,
but any good idea to change the white cct smoothly form the amber to warm white,nature white to blue white ?if so we can achieve the whole day sunlight,that would be cool idea,
and I have seen SK6812WWA digital white color chips,it is a real addressable white led which have 3 different cct white color chips inside, but I am not sure how to control different white color smoothly to achieve any cct white color.

looking forward to hearing good news,thx!
