These are some of the most powerful seals to use in ritual works. I use them all the time, along with bindrunes and Goetic sigils. They can be used alone with a candle or burned with herbs or carried around for protection or to bring money & abundance. You name it, there's a manner in which to use the seals for that purpose.
There are specific instructions regarding their use; colors, words, etc. In reference to the colors, the seals used are to be embroidered on a specific color & type of cloth with a specific color of thread. Now, most people can't embroider themselves and the cost of having it embroidered is more than most can afford. So, my suggestion, and what has worked just fine for me for years, is to print it out on paper in the color recommended. If you don't have a color printer, then print it out in black and trace with the correct colored marker or colored pencil or Crayon. It's the intent more than the actuality of it that really matters.
Now, that's not to say that going to extra mile of having it embroidered wouldn't be extraordinarily beneficial, and the energies placed in them very high due to the amount of time and effort necessary to bring the piece to the altar, but very few people can afford to have the seals embroidered every time they do a ritual. They cannot be re-used, they must be "new" seals each time.
The first 2 seals, the Magic Rod and the Goetic Circle, must be used with the chosen seal(s) for each work. These provide the foundation and strength for the intent of the work, which is empowered by the seal of intent (i.e. money, success, binding, etc.) These are also very beneficial to carry around with you at all times. (My own thoughts on this are that these would make awesome tattoos!)
There are also prayers to be recited before and after the ritual that open & close the doorway for the spirits of the seals to come through and do their work for the summoner.
