Closest to I don't mind or I don't care?

Question

In English there's a slight difference in meaning between I don't mind, which is a neutral expression of indifference and I don't care, which is a more negative expression. Which of these is Ça m'est égal closest to?

Just to add to Chris' excellent answer, 
ça m'est égal  = I don't mind/it doesn't matter to me
but also
 I don't care 
in a very mild way.
For a stronger sentiment, you would use 
je m'en moque
Je m'en fiche
Je n'en ai rien à faire 
 je m'en fous
(which is not as vulgar as the translation might imply but generates an interesting  noun 'le je m'en foutisme' which is used to describe a couldn't care less attitude)
and a lot more expressions with various degrees of vulgarity which I won't go into now!
But an interesting question, nevertheless...

Je m'en fiche.Je m'en moque.Both of these have a bit of a negative connotation. Along the lines of "I don't care."
