Remember, you don't need anything external to do Magick. The Magick is inside of you.
But, especially when you are just beginning, certain things can increase your desired effects of Magick (in very big ways).
This is because you are able to draw on the energies added by external tools (which each are imbued with their own energies). More importantly, you draw on the added belief these tools add to your subconscious mind.
Let's start with color - one of the most basic of energies that you can incorporate into your Magick.
The use of color in your spells can effect the outcome in two different ways.
First, are the Magick properties of the colors themselves. Each color reflects light in a different way, which is composed of a different energy that will have different effects on your Magick.
Here are a list of the colors you can use in your spells, and the type of Magick and how using each of them will effect your spells:
Black - use to ban negativity, in working with that which is hidden and in need of being revealed, in meditations on major life changes, and in connecting with Goddess/Mother energy.
Purple - use for psychic development, personal power, spirituality, prosperity, and connection with spirit world, success.
Green - use for growth, fertility/productivity, financial prosperity, earth connection, rejuvenation, and success.
Dark Green - use against greed and overly ambitious influences.
Bright Green - attracts love, social status, and fertility
Orange - use for energy, growth, and for drawing things toward you (as in drawing wealth toward you in ritual).
Blue - use for spirituality, wisdom, peace, harmony, and well-being.
Light Blue - use for serenity, peace, and stress reduction, meditations.
Dark Blue - use for prophetic dreams, need for laughter, increase of something.
Red - use for courage, love/passion, Father energy, health, and strength.
Gray - use for meditation, neutralizer, creates confusion.
Pink - use for romantic love, friendship, hope, rest, and relief from stress.
Gold - use for God, sun/masculine energy, and prosperity.
Indigo - use for deep meditations, stopping situations (such as gossip).
Brown - use for finding lost things, sometimes earth energy, concentration and study, prosperity, decision-making, and balance.
Magenta - use for higher frequencies, draws intense spiritual power for fast action, promotes spiritual healing.
Second, colors evoke different feelings and emotions within YOU. And the emotions they create can be different for each person. For example, maybe the color Red brings emotions of fear into you (for one reason or another). For another person, maybe the same color red evokes emotions of excitement and passion.
Simply do not use a color if it brings negative emotion to you, or none at all. Use the colors that deliver strong positive emotions of happiness, love, adventure, and excitement!
So use the specific Magick energies of colors above, and also use colors that bring strong positive emotions into your heart for spells filled with intense power.
