Active / passve - pentagrams, can anyone explain? Options

I just recently read somewhere about active and passive pentagrams.

the passive were you imagined as bluish colors and thast about it.
the active ones you traced in appropriate color (maybe red for fire or whatever) and also maybe placed the sign for fire in the middle of it.

Can anyone elaborate and explain more about this? I've used different techniques with and without these conditions but never figured anything about passive or active about them, just used however i felt like, so if anyone could explain more about this i could play more with rituals that require these.

When concerning the pentagrams there are only considered active or passive when it comes to the ones for spirit.

The Invoking Spirit Active pentagram is formed by starting at Fire and coming up to Air.
The Invoking Spirit Passive Pentagram is formed by starting at Earth and coming up to Water. The banishing pents are done in reverse of course.

As for the elemental pentagrams they are only formed one way and either invoke the element or banish it. The colors or symbols added does not matter. Only the element themselves are considered active or passive and they are always so. Fire and Air are active. That is their nature. Water and Earth are passive, that is also their nature. A little reflection upon the elements themselves will reveal why this is so.

I hope this helps.
