What is it
Hue is a huge pack of photorealistic gradients that you can use as content backdrops. Since creating Hue about half a year ago, I've used it for several projects. In fact, it turned out to be super useful - and I wanted to share it with you. Hue is completely free and made for Sketch. Feel free to use it for any personal or commercial project!
