thank you for the proposals. here are my very first comments:
- in general - i do not like the italics, and even more with bold...
- in general - but i like the dark grey + red combination
#17 - too simple
#18 - not this whay
#21 - the symbol - i think i understand the idea, but i am not sure if the audience would understand it, too. even i see there concret elements, the whole symbol is for me more abstract.
#19 - the green + dark grey is ok. the symbol is for me more like a hat and not like a credit card
