I like 39 since it is a bit brighter and easier to see but I like the blue in between the swoop from the a crossing to the e on 40.
Would this same look still work if the font had some more detail to it...? Also could you try in some other color combinations? You can utilize metallics such as gold, copper, and silver tones if that works with your design.
OK, here's my updates (#46, #47, #48, #49) for the color (silver & gold) revision based on#40 like your request. I'll come up again with another color (may be chopper). Please let me know if you need any other changes on it. Thanks
