The dominant species in Planet Blancneldos is the chamsonels. There are two types of chamsonels - logicians and philosophers. The chamsonels also have two different skin colors related to their veracity. Pink logician chamsonels always lie while blue logician chamsonels always tell the truth. Pink philosopher chamsonels always speak truthfully but blue philosopher chamsonels always speak falsely.

Here are the statements made by two of the inhabitants Antoninus and Boreas to a visitor from a neighboring planet who is color blind:

Antoninus: At least one of us is pink.
Boreas: That is not true!
Antoninus: We are both logicians.

What are the types of Antoninus and Boreas?

(In reply to Not sure...? by tomarken)

I also came to the same conclusion, yielding 2 possibilities:

1 (TFT):     Antonius = Blue Logician
                Boreas   = Pink Logician

2 (FTF):     Antonius = Blue Philosopher
                Boreas   = Blue Logician

Thus, at a minimum all we can say based on the given information in the problem, is that Antonius is always Blue, and Boreas is always a Logician!
