Hmm... The aqua one is the best in my opinion. It kind of makes you feel like you are underwater looking up. That last one is ok, but it doesn't compare to the blue one. The rest of them kind of stress your eye looking at it, especially the 2nd and 3rd one. They white in them makes it way too bright.
Definitely the agua one. It is a lot smoother than the rest. 2 and 3 look to sharp, and have way to much white. The blue one is balanced and does not really have a focal point. If you don't mind me asking, what did you make them in?
I really like the first one, the red, but I think it might be difficult to have that as a background and still have the writing in front of it be legible. For harmony between background and the font in the foreground, I like the second to last one, the blue.
Hmm, a lot of people are liking the one that was easiest to make, the third. Others liked the blue and red. I did this just experimenting, so yeah. Thanks to everyone who picked a color.
If a mod reads this, feel free to lock or delete this topic, as I don't need more opinions, although I wouldn't mind them.
Sorry Arax Nisanu, I missed your post the first time. I created them using GIMP. I just fooled around, and eventually got a basic picture, which I modified into colors and templates.
The second and fourth colors are great! Good background for a signature, and as a comparison, red can make people angry, while blue on the other hand soothes people and calms them. (Such as myself!)
