Well Purple heart is not really lavender to me but it is the only real purple wood I know of. When I have used it and finished it with an oil finish it has turned more of a cranberry color, pretty for sure, but not purple. And over time it will turn a deep brownish color. I have seen some purple tinted wood in popular but is is more like streaks than a piece of purple. So if you really want lavender like @Dave Monk, statedt to stay somewhere near lavender, paint is the only thing I know or some of the color from some other coloring media I am not familiar with. There are some weird named ones out there.. Oh, I just remembered one,,, unicorn spit, or something like that.
