Click on the color palette or the color presets to change the color. The svg export function is actually working but I have not implemented it into the user interface yet. I'm working on adding a color pallete with set colors so you can come back to the exact color more then once, and also being able to import your SVG back into your project to continue where you left off.
Thanks to W3Schools for providing documentation on the SVG format, and Wikipedia for showing how to convert HSV (What scratch uses for it's pen color/saturation/brightness blocks) to RGB (what SVG fies use)
