Sad to say in just one word, but it's ... boring.
Sorry, you asked for it. It's not original, it's not minimal, it's just a color gradient.
Someone before me already reviewed the "technique" - or so to say - so there's nothing much more to say.
I wouldn't know what to use it for - it's even too boring for my office desktop.
I never was a big fan of gradients but this one is just too foggy. I would think of a setting sun somewhere in a very, very, very far distance ... and a lot of fog that clouds the vision.
But I'm obviously not allowed to submit my critique unless it has at least 100 words.
So for some famous last words: I hope your next submission will be a little more ... visionary ... or original.
