The laces
False of course

Suggestion from Élise the 02/02/07 :
22
A little short this answer, and wrong!

Suggestion from CouSYouB the 02/03/07 :
Randomly, I would say 2 beacause we are in darkness, they will have inevitably the same colour!!! But we should not switch on the light!!!
You are true to yourself!

Suggestion from Dulotisse the 02/04/07 :
At most, if we are really unlucky, we are going to pull up to 20 laces of one colours. Thus it is enough to pull it one more, which will have necessarily the other one colour. Indeed we have to pull up 21 laces
Doesn't answer the terms...

Suggestion from CouSYouB the 02/02/07 :
To be sure to have 2 laces of the same colour, we pull the totality, thus 21 laces. Because there are 20 laces of each colour. Necessarily there will be most 20 laces of the same colour, and the 21th lace will be of the other colour
This method allows to be sure to have at least 2 laces with different colours...

Suggestion from Velesca the 04/09/07 :
21
Almost the same answer than the Élise's.
