We usually try to apply worst case scenario(which will be pseudo) and forget to find the optimal feasible solution,
Sufficient condition to get a pair of socks of same color is just 3, because after drawing 2 socks,
In worst case both of them will have different color and the third one to be drawn should make a pair with already available one of that color,
In best case drawing 2 itself would have fetch pair of same color.

So the answer is >2.

2 may be enough, but will not be sure.
3 is enough to get for sure.
16 is sufficient to the get pair of both the colors .

If these kind of question is asked in any interview then the answer should be number of different colors + 1.
That +1 to make pair.

So here the answer is 2+1 = 3
