This Orange County Fair website effectively uses a duotone (a 2-color image). As you can see, the banner carousel, composed of black and beige, halftone screen images (images made up of dots), gives the site a retro feel. In addition, the logo, set on a zigzag tag, adds visual interest. Furthermore, the image links, at the bottom half of the page, provide user friendly navigation. And finally, the headline text, set on an opaque red, reverse box, completes the balance of this site. Overall, nice design!
For old-fashioned, summertime fun – Visit the Fair, and use a Duotone in your website!
