See whether your screen can resolve all the dots in the userpic properly or whether you get “beats”, smushed areas, colour banding, or other artefacts :)
Incidentally, I’m a bit surprised that the GIF version of this image was nearly three times the size of the PNG version; my experience had been that for very small images, GIF can win. I guess that’s true only for sub-100-byte files where the size of the header starts to matter, compared to the compression ability.
Edit: saving the icon as a greyscale PNG instead of a palette one shaved another 1/6 off the filesize—now it’s under 100 bytes! (I’m a tad disappointed that the PNGOUT plugin didn’t do that for me in its “Auto” colour type setting.)
…I just realised that my (old) “colourcube-111” icon and my (fairly new) “Maxwell colour triangle” icon are essentially the same thing, just arranged slightly differently:
Edit: I’m intrigued by the fact that when I hover over the icons on Dreamwidth, I get a little hover window saying “This is you” and some links… even though it’s “just an image” and not specifically functioning as a userpic (next to my name in an entry, etc.). I suppose the code can’t know that :)
New userpic inspired by a post to CONLANG.
It’s a triangle with red/green/blue at the vertices and combinations of the colours in between. (For example, halfway along the red/blue side it’s magenta, i.e. 50% red and 50% blue, aka #FF00FF; and in the centre, it’s pure white, i.e. 33% red, 33% green, 33% blue, aka #FFFFFF. You could also find a spot that is, say, 27% red, 49% green, 24% blue, as long as the percentages add up to 100%; that would be something like #8CFF7D.)
(And my hands just typed "GZIP" instead...)
Here's a new Amy picture! For some reason, I've always used August pictures so far...
I'm not entirely happy with how the picture turned out when resized to a userpic, but we'll see whether I'll grow to like it (or whether I'll find a better one to replace it with).
