Changing the Color of a clay block

Is it possible to change the color of an already-placed clay block? With my code:

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
    public void onHit(ProjectileHitEvent e){
        BlockIterator iterator = new BlockIterator(e.getEntity().getWorld(), e.getEntity().getLocation().toVector(), e.getEntity().getVelocity().normalize(), 0.0D, 4);
        Block target = null;
        while (iterator.hasNext()) {
            target = iterator.next();
            if (target.getTypeId() != 0) {
            break;
            }
            }
            
            if (target.getType() == Material.CLAY) {
                target.getWorld().playEffect(target.getLocation(), Effect.EXTINGUISH, target.getTypeId());
                target.setType(Material.STAINED_CLAY);
            }
        }   
    }

which throws a projectile(code not included). When the projectile hits a block, it checks if it is a clay block, and if so, turns it into a blue clay block. The problem is with this part of code:

Code:

            if (target.getType() == Material.CLAY) {
                target.getWorld().playEffect(target.getLocation(), Effect.EXTINGUISH, target.getTypeId());
                target.setType(Material.STAINED_CLAY);
            }

I can't change the stained clay to BLUE_STAINED_CLAY as it doesn't exist and I can't add DyeColor to the end because .setType() only is applicable for Material.

So how would I change the clay to a blue stained clay? Thanks

 

block.setData((byte) 3);
Note: I'm not sure why you're coding this as I already made this for the person who requested the paintball gun. :S

 

Just for fun, I have a friend who wants this 2.

And is this the final code, or do I have to add anything to this?

 

@EpicCraft21 You simply have to use the setData method on a Block instance.
