Finding colour groups of blocks

[Vorlek]

you know in some games where you need to make groups of colours and stuff. a game i am making, i was wondering, is there an easy way to figure out where those groups are, and then do something with it, without having to enter in every combenation.

Just to show what i am doing, i am going to have 21 variables, that can either be a number of variables, they will be set up like this:
:v01 v02 v03
:v04 v05 v06
:v07 v08 v09
:v10 v11 v12
:v13 v14 v15
:v16 v17 v18
:v19 v20 v21

so basically if there are groups of colours in those variables, i need it to do delete those colours, from the variables.

I dont need the actually code to do it. I Just need to know the METHOD of doing it, you can help me with little bits of code if you want, but i dont neccecerrely need it, i can do that my self.

You should first learn to use arrays rather than variables. Arrays, in this case 2D arrays are extremely useful for block games.

rite, so i now have a basic idea of arrays, and i can get my game so that the blocks are in the arrays, and the actions read it and bring it up on the screen, instead of seperate variables (its pretty much the same as before but in an array), how do i get it so that it can get groups of 3 or more (up to 21)
Its still the same layout as earlier (3wide by 7high)

oh yes, i forgot to say, im using actionscript 3, i think arrays and stuff are the same as in as2 though. (Just in case though)
