Drupal.org has some useful links for web designers. This is adapted from it:
- Use Color schemes to make a color palette first.
- Create a favicon (that little icon by the web site name in the browser) with: favicon from pics or favicon generator.
- Does your screen design work for those with color blindness? Use Vischeck.
- Optimize your images to load faster on your pages: Yahoo! Smush It or Google Page Speed, or programs ImageOptim, PNGOUT, OptiPNG, or Pngcrush.
