Simple Nav Design
1. Create a new document, i recommend the nav between 800*50 - 800*150. but you can have any size you need or make a banner out of the style.
2. Now fill the background with the color of your choice.
3. Now open up the blending options and use these settings:
4. Make a new layer, select the top half of the nav. Fill the selection with white.
5. Lower the opacity of the white bar untill u get a look u like.
6. Add text, mouseovers anything you want to finish it off.
Final Result
