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.

What nero sais is completely true.

I will still make some graphics, but you will have to wait some longer.
I am very busy at the moment and don't have much time. but be patient, I will draw something for it.

I gotto go, I'm gonna click one more time on the google adds down here, i suggest you do the same.
