I have upgraded from fedora 21 (with plasma 4 and oxygen icon theme) to fedora 23 with (plasma 5 and breeze icon theme) recently, and even after allowing for some time to get used to the new icons, I still cannot read easily what is the reception level of my wifi or the set volume of the speakers at a glance: the volume has two bars and the wifi has three, and each bar can be either black or grey, but the black and grey are so close that it is impossible to tell them apart without squirting at the screen.

This is a big regression after coming from the oxygen icons, where an unset bar was hollowed and a set bar was painted in white: reading the levels was immediate. The breeze icons for the volume and wifi reception need more contrast, either by changing the grey level of the unset bars, or making them dash lines, or making bolder the set bars.

Note that this is not a criticism about the breeze design; it is a bug about how two icons which should convey easily important information fail to convey that information. To take an exemple, I find that the battery indicator does a great job (better than the oxygen icon) to tell me at glance the battery level.

It is important that the breeze icon set be flawless because there is no alternative. I tried, because of the current issue, to use the oxygen icons but it is impossible because some icons are missing (such that, for instance, the wifi killswitch and airport mode icons in the pop-up menu).

Reproducible: Always
