Some airbrussh output is "invisible" in certain terminal color schemes

[mattbrictson]

We've received multiple reports (from @Startouf and @dan-klasson in capistrano/capistrano#1669) that important error messages are not being rendered by Airbrussh.

Specifically, the color of the message is indistinguishable from the background color of the terminal, making them "invisible".

Suggestions of how to reproduce this (what OS and terminal is affected?) and how to fix it would be greatly appreciated.

Same issue here. I'm using the 'Solarized' Color Scheme of KDE's Konsole in version 15.08.0 as provided by Ubuntu 15.10.

Thanks for the additional data points.

Can both of you run this simple script in irb and post a screenshot of your output?

gem "airbrussh", "1.0.2"
require "airbrussh/colors"
Airbrussh::Colors::ANSI_CODES.keys.each do |color|
  puts Airbrussh::Colors.public_send(color, color)
end

Here's what I see:

Only solarized has the issue. Even solarized light uses a proper gray:

So it's probably an issue with the solarized theme.

[mattbrictson]

Great, looks like we've got this figured out.

I know that solarized is popular, and I don't want Airbrussh to obscure important messages when people are using it with solarized. I think that warrants changing Airbrussh's default colors (even if solarized is ultimately at fault).

Do you agree?

Right now Airbrussh uses the gray to display info log messages (e.g. "linked file does not exist", upload progress, etc.), and also the time elapsed for each command. If we don't use gray for those because of the solarized issue, what color should we use instead?

[huerlisi]

Cool!

I'd go with the default color, like the irb output.

[mattbrictson]

Any chance you'd be willing to do a PR? It should just be a matter of removing the use of gray from command_formatter.rb and console_formatter.rb and then updating the expected output in the tests.

[huerlisi]

Yepp, can give it a try:-)

[huerlisi]

PR created, please review:-)

@dan-klasson maybe you want to also file an issue in Gnome and link this and the KDE bug.
