Kamvas 16 display problem

I've had this tablet for a few months now and ever since I started using it I had with colors. My tablet displays colors a bit darker than what my laptop shows. So whenever I pickec out colors and used them, they've been either too bright or too dark than what I've seen on my tablet. At first I thought that I could cope with it but now it seems rather annoying. Is there any way to fix that? I've never had display tablet before.
