The half blue / half green image still looks better with LQIP than BlurHash. I was getting ready to use BlurHash in my app, might try this instead!

In fact, LQIP looks better than most of the BlurHash examples in the gallery (https://leanrada.com/notes/css-only-lqip/gallery/); not sure if these were cherry picked or what.

Author here: Definitely cherry picked ;)

I did deliberately pick some "bad" examples like the blue+green image, and other multicolor images.

I wanted to add an upload function so people could test any image, then i realised I'd have to implement the compression/hashing in the client. Maybe i should!
