Which one do you like? The patch (so far) contains Konsole and Yakuake icons, 48px, variant A. Personally I like variant C for Konsole the most.
Note that in T10243 I've published following version, with slightly different colors:
If you like these colors (especially dark bg), I can use them.
Todo after deciding on the design:
- update sizes other than 48px
- add/change the Konsole and Yakuake icons in the icons-dark directory.
