Talk:Defective coloring

Some comments
I'm not a fan of referring to the concept of (k,d)-colouring in the *History* section before it is actually defined.

Also, pardon me if I misunderstood the definition, but it seems that we should have $$\chi_1(C_5) = 2$$, since we could colour it RBRBR, and that would be a valid (2,1)-colouring. --Jordan Mitchell Barrett (talk) 21:25, 21 December 2019 (UTC)
