You, sir, lack an appreciation of minimalism. ;-)
There's a fine line between minimalistic and really, really ugly.
Just saying.
Minimalism, as anything else in the realm of aesthetics, can be done competently as well as badly. Yes. Even if there's little else I seem to be able to agree with you on ;-), I think we can agree on that.
We can probably also agree that there is *some* amount of individual leeway in judging questions of aesthetics. I wouldn't go so far as to say that aesthetics is entirely relative - there are some fairly fundamental 'rules' for what human beings tend to find attractive, in terms of proportions, colour combinations and whatnot - but there's definitely some flexibility there. (Although you may disagree with me there, I dunno. You seem very strict in your judgements, so maybe you believe that your aesthetics is the One True Aesthetics, and everybody else is just Wrong?)
Me, I happen to be rather flexible in my aesthetic preferences. I like Bauhaus architecture; I like medieval book illumination - just to give two examples. I like some very different, in fact: diametrically opposed, aesthetic styles. And part of the joy of KS for me is being able to play around with some very different looks/styles.
Anyway, to get back to my beloved screen 2 ;-): for me, that screen works extremely well, meaning, it makes the aesthetics synapses in my brain fire in all the right ways - and I even have a fairly good idea why it works so well:
- The colours - the dark red background, the brighter red foreground, and the white-and-red highlights provided by the flowers - go well together.
- The screen has a good amount of contrast between the background and the foreground, the background and the flowers, and the foreground and the flowers, while still preserving a monochrome general impression. This means that the overall impression is harmonic, with the contrast saving it from becoming dull. Also, the contrast makes the flowers stand out nicely.
- The proportions and placement of elements, both in terms of colour and shape, are pretty good. Just enough symmetry - in the vague diagonal described by the tunnel - to orient the eye, but enough asymmetry to keep things interesting; etc.
Everybody's free to disagree, of course. As I said - there's definitely some amount of individual taste involved in judging things like this.
