Brothers Crossed Eye Color Puzzle (Posted on 2022-07-20) Difficulty: 3 of 5
Amos, Bert, and Clem are brothers. It is known that:
  1. Amos has exactly two brothers with grey eyes.
  2. Bert has exactly two brothers with grey or hazel eyes.
  3. Clem has exactly two brothers who do not have blue eyes.
  4. At least one of the three has hazel eyes and at least one of the three has blue eyes.
Whose eyes do you know the color of?

Some Thoughts Assuming ... | Comment 1 of 7
Assuming there are only the three brothers, and assuming each brother's left eye and right eye are the same color:
B grey
C grey
A grey or hazel
C grey or hazel
A not blue
B not blue

A:  grey or hazel; not blue
B:  grey; not blue
C:  grey; grey or hazel

With the above assumption: We know B and C have grey eyes.

But if there is a either a 4th brother, or anyone has heterochromia, then this conclusion is likely not valid and a deeper analysis will be needed.
This is therefore, in my opinion, not a full solution.

[Edit:  this is in error, I was not taking the 4th condition into account.]
