How do I check what color a wool block is?

I need it so my plugin checks what color wool block was placed or destroyed. This is what I have so far:

Code:

@EventHandler
public void blockPlace(BlockPlaceEvent e) {
    if(playersInGame.contains(e.getPlayer())) {
 
      //players in game is a hashmap I use.
 
      Block b = e.getBlock();
      if(b.getType() != Material.WOOL) {
          e.setCancelled(true);
      }

How do I check if the wool block is like blue?

 

b.getData();
returns a byte.

 

Can you show me it being used somehow.

 

I think you need to check if the data equals the color code of blue wool.

EDIT: Link to wool data values: http://www.minecraftwiki.net/wiki/Wool#Data_values_for_colored_wool

 

Code:java

if(b.getState().getData() instanceof Wool)
{
    DyeColor color = ((Wool)b.getState().getData()).getColor();
    if(color == DyeColor.BLACK)
    {
        // its black :3
    }
}

Just saying :3

 

An alternate way to do this:

Code:java

HashMap<Int, String> hm = new HashMap<Int, String>();
hm.put(0, WHITE);
hm.put(1, ORANGE);
// etc.
String color = hm.get(b.getDurability);

This could, of course, be easily modified to return a color rather than a string. I would use this code f your goal is to get the color of the wool, rather than check if it is a certain value.
