Show HN: Generate random gradients like on OpenAI's website (opens in new tab)

Hey HN!

Check out this fun tool I built to make cover images for my blog. The main goal: interesting looking random gradients, that all draw from a single color palette.

I stumbled upon this post from Justin Jay Wang [1], who designed for OpenAI - describing methods for random gradients, including the one that shipped on OpenAI’s homepage from 2020-2022.

Since the post included ~10 SVGs, I was able to reverse engineer the SVG parameters, and decided to put up a generator. You can see the exact deets in my Github README [2].

I also use it to generate cover images for my Substack [3] - if you want to see what using a bunch of images generated by it looks like.

I think Noise will make it better.

This is great but I wish CSS output was generated. Anything that can do that?

Nice work. Gradients can add a dynamic feel without distracting users, and OpenAI’s subtle animated style is a good example. A generator like this makes it easy to experiment with color palettes and get consistent, visually pleasing results quickly.
