Some icons are based on Breathe theme from http://kde-look.org/content/show.php/Breathe?content=133873&foo=53fa9b6299cabbf8a0fc35b1016903c8

To use icons for KDE applications, copy files from "kde-tray" directory to /usr/share/kde4/apps/desktoptheme/-YOUR-PLASMA-THEME-/icons/ (for Air theme - "default") and restart plasma-desktop.
To use Psi icons, copy crystal-whitray.jisp to /usr/share/psi-plus/iconsets/roster (for psi-plus, replace "psi" with "psi-plus") and select this iconset from preferences.
To use Dropbox icons, copy files from "dropbox" directory to /usr/lib/dropbox/icons/hicolor/16x16/status/

Tips:
  When using Whitray theme with Psi, you may want to use another roster theme for displaying icons in program (as black&white icons are pretty, but only on system tray).
  To do that:
    Psi -> Options -> Appearance -> Icons -> Roster Icons -> Custom -> Add:
      Regular expression: .*
      Iconset: Select your theme (for instance, Crystal (Roster))

    If you want to set different themes for different services, use "Custom" tab instead of "Services" and use regexps:
      For instance, for Gadu-Gadu transports: .*@gg\..*
      For server and transport entries: ^[^@]*$
