If you're working with a vector file (SVG) or an image file (PNG), you can easily change the color. I do recommend starting with a black image if possible (it's the easiest to make straight color changes). In this video, I cover how to change the color for both vectors and images.
Inkscape is a completely free vector software tool similar to Adobe Illustrator. You can download it here:
