I couldn't believe what I just read, when you started this thread. I was gonna say something like " Are you crazy?" But then I thought you just need to be informed a bit, not told off.
Every colour and culture has magickal roots, all over the world.
And like Darkart was wise enough to say - 'African witch doctors'.
Where do you think hoodoo and voodoo come from? Theres magick in everyones cultural background and Gods and Godesses of every colour from the beautiful norse Godess Freya to the equally beautiful African voodoo Godess Erzulie.
Please do not for one minute think that the colour of your skin is going to hinder you in doing magick because, it won't at all.
And it doesn't matter what area of magick you go into, as anyone of any race can explore what area of magick they like. I have a blonde haired, blue eyed irish friend who's into native american magick and culture. Do not for one minute put those sort of limits on yourself.
Study magick by using google and reading, meditate regularly, practise visualization and don't be afraid to ask questions on here. The more you progress, you will see results.
Goodluck and many blessings to you
