All colour pickers actually have discrete steps.  I think the answer 
depends on why you have used visually obvious discrete steps and how 
important it is to get the exact colour.

Again, depending on why the colour is being selected, you may need to 
consider defective colour vision and even the normal variations 
resulting from how the eye works and how the colours are generated by 
the display.

I would think that the reason that Word uses clearly discrete steps is 
that users expect to be able to repeatably select the same colour, and 
it is more important that colours are consistent than that they exactly 
match something outside the Microsoft Office universe.  In that case, 
the ability to select a specific square is critical, and the squares 
need to be large enough to achieve that, or other means need to be provided.

 From more of a usablity point of view, you need to consider whether a 
specific exact colour needs to be entered.  E.g. sometimes I need to 
match a specific pixel, elsewhere on the screen.  Colour gradients only 
allow approximate colours, as perceived by the user.
