I like this one for the simplicity. However, I'd like to see some other colors in the design. Such as changing the .IO or the word "barcode" to a different color. Also, perhaps change the entire word to lowercase would help too (along with color alterations). Thanks!
Uploaded. I thought about making ,,code" from some bottle or glass symbol. But i saw one code logo with beer glass. So I think it will be better stay with letter B.
