I recently came across IssueHunt and noticed a feature request in Gifski that I could work on. The PR hasn’t been merged yet, so I can’t say much about the entire process, but I like the idea of attaching a bounty to issues in open source projects.
I’m considering making an app that allows designers to easily pick and use vibrant/primary/dominant colors from an image. The following projects look like great starting points. I’ve updated one and added support for macOS to the other.
