Accessibility

So, I've been playing for a while and I've been looking in the settings, but haven't found an answer. Is there a way to change your cursor in-game? It's very hard for me to see, the size and colour of it is not very accessible when it comes to vision problems. Makes it quite hard to see, especially if the background of what you're looking at is completely white. In the menu it's fine, it's only horrid in-game.
