I think it is clear that adding a border is a solution to the usability problem i describe. It sounds like you find it an undesirable one due to the impact on icon style. I certainly appreciate(d) the advantages of the 'glyph icon' solution.
According to your description of the intents of humanity-dark, by using a grey taskbar, i guess i was using the icons 'out of spec'. In that context, the problem with humanity-Dark is not so grave. Even with the task bar black, contrast is sufficiently low in some viewing conditions, that i suggest brightening. Whether it would be part of Humanity or not, i think there is a need for a solution for the general problem of a varying background colour, because i don't think there will ever be sufficient coordination among icons provided by independent applications. That general problem can be addressed with borders. With Humanity, 2 use cases are covered. That is a choice with reason behind it and is better than some other icons. As a side note, if a reader should ever consider making a version with borders, you can have the borders have a transparency gradient — if it suits your sense of style. Review/Summary according to self: Use case in bug was invalid. nonetheless the problem of insufficient contrast is present, even under valid viewing conditions. Want of a general solution is 'wish list' and not necessarily part of this bug report, because Humanity is not intended to provide that general solution. -- panel icon has visibility and poor contrast against some backgrounds https://bugs.launchpad.net/bugs/494639 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
