easy color question (I think/hope)

The heck do you call those dots and how do you change the color so I can see them:
 

 
I feel like they are under the color preferences I just can't seem to find them.

Thank you!  Much better.  And yes I never would have found it by that name.  I would have just named them "dots" or something.

When I can't find something no like that - I just go down the list, changing things to bright red - until the right object changes ;-)

Then I reload my colour preset (getting rid of all the red crap) and now I know what setting to change ;-)
