fillStyle not a function

Question

I'm getting an unusual error:

ctx_wrap.fillStyle is not a function

on this line:

ctx_wrap.fillStyle('#b8b8b8');

in here:

...
this.paint = function() {
    self.path(ctx_wrap);
    if (!isOver) {
        ctx_wrap.fillStyle('#b8b8b8');
    } else {
        ctx_wrap.fillStyle('#d6d6d6'); 
    }
    ctx_wrap.fill()
    ctx_wrap.stroke();
};
...

What is strange is that, if I comment out that line, the line beneath works. These two lines are nearly identical, but the first one produces the error and the second one works:

ctx_wrap.fillStyle('#b8b8b8');
ctx_wrap.fillStyle('#d6d6d6');

Why would the first line produce the error?

Answer 1

Try using ctx_wrap.fillStyle = "#COLOR".

The second one does not work, the console just stops at the first one and spits out the error, because it freaked out from the line of code.
