In my humble opinion.... 3 is almost perfect in color balance. Try taking the steem logo (squigly lines) and just the word Steemstock from 2 and replacing it in 3. Does that make sense?

So basically the font size SteemStock from #2 and replacing it with #3
(squiggly lines) from #2 and replacing it with #3 (The squigly lines in #2 seem richer or darker in tone)
The circle size in #3 is perfect...color of bird as well.
Hopefully this helps.
