I'm trying to create an `SKSpriteNode` with an image from the SF Symbols font, and while I can do it, I can't seem to make it any color other than black.

Here's my code:

```
let image = UIImage.init(systemName: "gear")
let colored = image!.withTintColor(.red)
let texture = SKTexture.init(image: colored)
let sprite = SKSpriteNode.init(texture: texture, size: CGSize.init(width: 32, height: 32))

```

Unfortunately, the resultant sprite always comes out in black (and not red).

What am I doing wrong?
