I adjusted by using convert > screenie.png -gamma .454545 tmp.png; convert tmp.png -gamma 3.0 > Screenshot-gamma3.png That screenshot looks very similar to the grey (#252525) text to me (on the same monitor). That's the main problem I'm trying to get at, though - gamma is an issue, but there's a lot more to it than just the gamma. Even with differences in gamma, defined black and white do tend to look pretty similar across devices (some may be brighter or more black than others, but it is basically still black and white), but how the contrast is handled in between those colours may be completely different, resulting in the appearance of greys varying wildly. They can potentially show up as anything between black and white, or even just AS black or white. Examples: * #444: Looks like a good dark grey background colour for displaying images against (because it won't distract from the image, but will still result in enough contrast to make out any black elements) on one screen. Just looks black on another. #888, on the other hand, looks the same on both. So does #eee. * #f6f6f6: Used, along with some light blue, to make the gradients in the vector skin. Completely indistinguishable from white on one monitor. Tabs are only distinguished by a small visible part of the blue gradient and the borders, and even those are hard to make out. * #222: Looks the same as #444 on one monitor. Obviously not the same colour. These are monitors I have and use. Out of six, six are kind of crappy, just in different ways (dead pixel, off red intensity, the above examples of weird contrast; it varies), but these are also fairly standard consumer models (three of them were apparently top-rated on newegg, or got labelled with some sort of award there). Unfortunately, while monitors are adjustable, because the hardware/software of/for the device itself generally isn't very good in the first place, solving for one problem usually just winds up with another. Some problems, of course, are much more preferable to others (such as an overall level of contrast that doesn't hurt the eyes, or a level of darkness that makes playing <insert popular game title here> the most enjoyable), but there will always be problems. Here's the thing, though - we don't CARE if the subtleties of the vector skin are getting lost for some people, or that the background colour a lightbox uses just looks black on some displays. That doesn't really matter, because that stuff is really just decoration. It'd be nice if people could see it, but if not, whatever. Text, though, we need people to be able to see well. Always. -- You are receiving this mail because: You are the assignee for the bug.
