Hi,
I'm just starting out with home made espresso and this is my first post, although read many.
i am gradually getting better at making espresso however i notice that after i pull a shot (my terminology may not be accurate)
and stop the pump, coffee will drip from the portafilter spout for some time. is this usual?
I have a Gaggia color with a standard portafilter and am using the double shot basket.

Many thanks for any advise

Sean

Welcome to CG forums.  I believe that the Color does not have a 3 way solenoid valve and therefore does not release pressure from the brew immediately, compare to the Gaggia Classic.  This means that the pressure and a bit of liquid bleeds off through the puck and drips.  You may also find that the portafilter remains very tight for a minute until that happens.  If you manage to loosen it early you will be rewarded with a hot sprayed mess so do not try.  It sounds like it is working normally.

+1 this is something that will just happen regardless if you don't have a 3 way valve.  I used to have a little Delonghi and I was always in a rush when I made espresso.  I used to kick on the steam for a minute after I pulled a shot to heat up the portafilter and dry out the puck.  Granted I was using an aluminum portafilter.  Yours is brass so it may take longer.
