But here's the scoop on the SF patch....
The "Airborne" tab goes along with the unit patch... the Airborne tab becomes part of the unit patch for units on jump status. Since Special Forces groups are by definition jump-qualified units, everyone assigned to a Special Forces Group wears the arrow patch with the Airborne tab, regardless of whether they're airborne or Special Forces qualified. You could be a "leg" (non-parachutist qualified person) with a job like clerk or a cook for a SF unit, and you still wear the arrowhead and Airborne tab.
Only those who have been through the Q course and are thus Special Forces qualified get to wear the SF tab.
like this, in blue with yellow lettering Once you earn your SF tab, you keep it forever, regardless of where you're assigned. You'll occassionally also see a "triple tabber" (someone who has completed both Ranger and SF school and is currently assigned to an SF unit) who will have the Airborne tab, with the Ranger tab above that, and the SF tab above that.
Now, as for berets. Regardless of the color, every beret will have a flash and crest. The flash is the cloth patch, most units which wore berets in the days before everyone in the Army was issued one have a distinct unit flash. This is what the 5th Special Forces Group flash with the Special Forces crest looks like...

Now, as for beret color. The generic beret color for anyone in the army is black. That used to be the color the 75th Ranger Regiment used to wear, now the Rangers wear tan berets. To earn a different colored beret, you both need to complete certain qualification courses AND be assigned to a unit which that qualification refers to. Everyone who serves in a unit designated as airborne is entitled to wear the maroon beret, regardless of jump status. Those who are serving in SF or Ranger units but are have not earned their SF/Ranger tabs also wear maroon berets. Only those who have completed SF training AND are serving in a SF unit get to wear green berets. To wear the tan beret, one must have both completed Ranger school AND be assigned to a Ranger unit.
Like i said, once you earn the tab it's yours to keep forever, but the beret is premised on maintaining your qualification status and serving in a unit designated as belonging to either a SF Group or 75th Ranger Regiment.
