I do not have a color wheel.
Yes, you do. Open the Apple Colour Palette and choose the leftmost palette mode, Colour Wheel.
I have the basic RGB, CMYK, HSB, and grayscale?
Yes, these are the colourant models / colourant formats that can be colour managed.
I would like to have ... Web safe colors.
Yes, you have Web Safe colours. Open the Apple Colour Palette and choose the middle palette mode, Colour Palettes, then open the drop-down list and choose Web Safe Colours (which is in fact a colour managed NMCL Named Colour list profile).
I would like to have other palates I can use, such as Pantone, Trumatch,
No, you cannot colour manage these colourant models / colourant formats. They are premixed and form the intended colours if and only if you precisely duplicate the intended printing conditions (intended paper, intended tone value increase, intended ink set). That is, these colourant combinations are not 'portable' or 'repurposable' from one printing condition to another nor are they defined if you deviate, that is, if you were to use a named colour profile for them, which you could in principle do, that named colour profile would apply if and only if you used the colour definitions for conditions at which the colourants were laid down at 100% as intended. If you used the colour definitions for a 75% tint of Pantone XXX or Trumatch YYY, you would have no predictable colour definition any more.
Peter Breis still does not get to base one on the portability of spot versus process in paginated publishing -:)
