Show HN: ColorizePhoto.com – WebGL Based Photo Colorizing Tool

I just saw the front page post about automatically colorizing photos (https://news.ycombinator.com/item?id=10864801) and thought I should share this website I built a couple years ago. It allows grabbing color from a reference photo and painting it onto the black and white image you wish to color. It was a fun learning experience and can make some pretty convincing photos with a bit of patience.
