I use pywal with the variety wallpaper changer to automatically change the color scheme of urxvt. I have all this happening in the background and set to a one hour interval. I also have a hot key assigned in my i3 config file so that i can make all this happen whenever I like as well. This all really cool, and I will probably submit a post one day explaining all that in case anyone is interested, but having a terminal color scheme that changes based on the colors in your wallpaper on an hourly basis can wreak havoc sometimes; stuff like syntax highlighting in vim, and tmux status bars can sometimes become hard to read when the colors switch to a less than ideal scheme.
While I have not taken the time to fix the issue with vim, as I don’t always use syntax highlighting, I have fixed the issue with tmux. As an aside, I was a GNU screen user for many years, but switched to tmux 4 or 5 years ago. Anyway, back to tmux, the issue I was having was that the status bar in tmux would change to a color scheme that would sometimes make the window names difficult to read.
The solution I stumbled upon was a one line addition to my .tmux.conf file:
setw -g window-status-current-style bg=black,fg=white,bright
This fixed the issue completely, and additionally (with the fg set to white, bright) makes the current window the most easily read.
While this is most definitely a self-inflicted problem, as I don’t really need to have the color scheme based on the current wallpaper, and have it change hourly, I do like the variety, and I am glad I have found a workaround.
