Dear Ms. Q,
The simple answer is Yes.
If you are writing your spell on a color paper, tieing it with a color thread, writing it with a color ink, using a color cloth the answer holds true.
But I need to do a caveat to that, I say it holds true and has worked for me and for others who have done the same thing. Only by trying it out and having faith in it can it work for you.
For some people having plain fresh white paper and just using a color ink and then anonting it with a specific oil works for them, or using brown paper that has never known a scissors, such as a brown paper bag and you simply tear the edges works for them, avoiding the use of metals, this I've seen work on love spells.
For some people using speicialized inks such as Dove's Blood, Dragon's Blood, Bat's Blood for the speicific spell, and then tying it with a colored thread, (embrodery thread works well) works for them.
It's like a cooking recipe or science experiment, your hypothosis could make the spell work, depending upon what you are feeling, or in some cases what you have on hand.
So the colors that I list can be applied to certain applications or spells or magikal workings.
Some people take it a step further, they have specific colored books for specific spells, Green for fertility and posperity, Red for passion and lustful romance or bringing a particular person into your sphere, pink for soft romance and love, Yellow for creativity, Blue for healing, Black---well for the worst kinds of things.
But you get the idea.
Later on I will cover other things like types of candles, how to dress a candle, reversing candles.
Blessings Ms. Q
