Following Blender Guru's Donut Tutorials and currently at the end of Part 1.

I'm really unsure about the false color concepts, grey is the ideal color so we have to tweak all the settings till its mostly grey?? Based on what I have read, this works like a heat map; so red and dark blue should be avoided at all cost??

Using cycles with basic settings.

Generally, just try to avoid pure White and pure Black areas

  • White represents High end clipping - you lose details for anything brighter
  • Black represents Low End clipping - you lose details for anything darker

Three things to remember:

  1. You can always increase clipping later, but you can't recover clipped details from exported JPG/TIFF/PNG
  2. Keep as much details for editing and only clip colors in your final photo
  3. You can have as much clipping in your final photo as you want, there's no right or wrong

Here's a detailed chart of the values for the coloring for the false color:

    $\begingroup$ @JacymMichal. Instead of altering exposure for the scene, it would be advisable to modify the light sources' levels to accomodate the desired values. Or in the case of HDR used as environment lighting, modify the brightness there. $\endgroup$ – susu Sep 27 '20 at 19:20

wherever there is red color in this heat map , there is so light getting reflected that the exposure is making it almost impossible to see , and blue is so underexposed that it looses its detailed and is totally dark.
