Currently, konsole.kde.org is showing official icon for Konsole.
On the other hand, Plasma uses by default the Breeze icon for Konsole. That same icon is also used in the screenshots themselves in the same website. The Breeze icon is generally more recognizable, especially to recent users, and maybe could create a stronger brand. Also, since Plasma is using Breeze as default theme, I think this icons feels more Plasma-related.
Which icon do you think should konsole.kde.org website use?
