  close - what you are describing is called color temperature; the hotter an object burns the more the light emitted shifts from yellow(ish) at 2500K like a campfire to blue(ish) at 6500K like bright daylight
  our circadian rhythm is influenced by a large part by the wavelength of the light hitting our eyes.
  while warmer light (think sunset) releases all the good stuff that gets you relaxed and ready for sleep, the blueish white light (daylight) tells our lizard brain that it is time to be alert and go hunting
  that is exactly the same reason why you should not use a device with a screen before you go to bed and a lot of devices have a „blue light filter“ for the evening
