Any advise for a good colour wheel design tool?

Hi, I was wondering if any of you use a colour wheel design tool to help with your projects? If you do, which ones do you use?

I've noticed that there aren't many available for the Mac, however, I have found that these ones:

Are there are more?

Thanks.
