The colour of the voodoo doll it's self is often only present to represent the person the doll was created for. For example: if the doll was made to help heal someone who's favorite colour is pink, then the doll would be made to be wearing the colour pink.
However if pink pin is used, the meaning behind a pink pin is death.
Blue=love
Red=Pain, Brocken bones
Pink=Death
Yellow=money
White=heal
Black=sick

usually means that the victim targeted by the voodoo doll will die. this is the worst type of voodoo doll. From the dominican republic and they throw them in the ocean to curse those who receive it upon other shores.
Voodoo dolls are generally created to represent a specific person. If the doll is tan it may be because the person it is made to symbolized likes or wears a lot of tan.
The most popular sterotype of using a Voodoo doll involves sticking pins into it.
I wouldn't consider Robert to be a voodoo doll, but he is a haunted doll. And yes, he is real.
If it is your voodoo doll (not one that belongs to someone else, or one you have found.) Then unraveling the voodoo doll is a way to undo or end the conjure, if there is one in place with the doll.

Sources say to see a voodoo doll in one's dreams is to see a primitive aspect of one's self. However if you see a voodoo doll upon waking, I think it simply means you saw a voodoo doll. Not everything has an underlying meaning.

During your upkeep you put a pin counter on Voodoo Doll. If Voodoo Doll is untapped at the end of your turn it deal damage to it's controller equeal to the number of counters. You can pay double the amount of counters on Voodoo Doll, and tap Voodoo Doll to deal damage to target creature or player. Lets take the scenario that it is the beginning of your turn and there are currently 3 pin counters on Voodoo Doll. During your upkeep put a pin counter on Voodoo Doll (4 counters) At any time during your turn (when you can play an instant effect) you can pay 8 mana, tap Voodoo Doll and deal 4 damage to a target creature or player. If Voodoo Doll remains untapped at the end of your turn, you will take 4 damage and Voodoo Doll will be destroyed. You do not have to use the Voodoo Doll's ability, all you need is for Voodoo Doll to be tapped at the end of your turn. You could tap it with a fast effect, or use a spell to turn it into a creature and attack. There are a vast assortment of ways to prevent Voodoo Doll from dealing you damage. Personally i would suggest that you get a better 6 drop card. :) Good Luck (may you never be mana screwed)
The amount of pins used in a voodoo doll depends entirely on the purpose of the focus.
