That`s, unfortunately, one drawback with websites....your site may look 20 different ways on 20 different computers.
Web designers used to stick to "web safe" colors...but with a palette of only 216 colors...that was very restrictive. We`ve essentially thrown out the web safe color pallete since most people are now using monitors that support millions of colors.
Another issue is web browsers. Often, a site may look different on Internet Explorer vs. Firefox (the best browser for web standards) or vs. Macintosh Safari...etc. And don`t get me started on screen resolutions! (please...all you remaining 800x600 people...please up your resolution one notch to 1024x768..... :)
Because the end-user ultimately has control over many aspects of how web pages are displayed, we have to accept that our designs will look slightly different depending on the computer, etc. The good news is that people are more concerned with how your site functions...rather than how your site looks. (here`s an article from a great site that talks a bit about web user behavior ...read the paragraph under the Success = Fun heading. )
Best of luck to you.
This happens sometimes with incorrect monitor drivers being installed. Make sure your husband has the correct drivers (brand and model).
Also if he`s using Windows, go to Control panel->Display->Settings tab and check the "color settings" (16 bit, 32 bit?) and you can compare that with your laptop and LCD settings.
Your website shows perfectly at my end....I like the design and colors very much!
p.s - Thanks Brian for the web safe colors link :)
