This is good to know -- the icon for the app I am working on is blue as well, now I am considering changing it!<p>As a coder who understands UXP but is not great with design, I often fall back on blues or grays for my projects. For whatever reason I find that designs I make tend to look better in blue than other colors. Reds too often look pink, oranges and yellows are hard to keep from looking overpowering. Greens aren't too bad, but I still have trouble getting it to look just "right." Maybe it is just me.
I disagree with this. I actually really like the asthetic of having a mostly blue selection screen, rather than the jumble of clashing colors. I won't go so far as to say that one SHOULD use blue, but I don't believe there is anything wrong with it.<p>I would actually argue to stay away from the color black. Looking at my current home pane, I tend to forget that I have AirCam and Rev, AirCam in particular because it melts the most into the black backdrop.
I thought it was old news that blue was the unofficial 'color of technology'? icons, logos, even LEDs: If you need to look high-geek, blue is the way to go.<p>That said, none of the icon pages on my iphone are dominated by a single color. The closest I get is one page with just under half the icons being mostly <i>brown</i>, which surprised even me.
It could have used some more info… On one of my screens I have a lot of red icons. It's probably just depending on what YOU use.<p>But that's something I have noticed for the Mac as well: a lot of the icons I have are in the blue-purple range. Again, probably because of what <i>I</i> use.
