First, you need to define what you mean as “day”. You can do this based on fixed times (e.g. if you wake up and go to bed at given times), or based on the sun position (i.e. day is from sunrise to sunset).
Then, if you want adjustment during the day, you should pick one of the “day only” options. You can try both functions, although I think that the half-sine looks a bit better (when I get some free time, I will prepare some graphs to show how it works).
Unfortunately, the blueprint can’t automatically switch from white temperature in the day to rgb colour in the night. This would make it even more complicated than it already is. Still, if you have a light that does both white temperature and rgb colour, whenever you switch colour mode manually, the automation will continue to adjust it. When the light is in white temperature mode, the automation will adjust its brightness and temperature, and when it is in colour mode, it will adjust its brightness and colour hue. For lights that have brightness mode only, it will only adjust the brightness. And for simple switch lights, it will only turn them on or off.
Finally, it is expected for the automation to stop adjusting the light when you change it manually. This is done on purpose. For example, it would adjust my living room lights based on my routine, but when I have friends at home, I would simply increase the brightness and it would stay there.
I hope this helps, but please do let me know if you need any further clarifications.
