Hey Linda........I would try Glidden.com - you should be able to find a color similar to the color of your brick that will give you ideas.
Also, there is a CD-ROM available at The Home Depot called Glidden Color@HomeII. I does the same thing as the website (allows you to import a picture of your house or room). It costs $5.97.
My other suggestion would be (and I'm sorry I can't be specific - it is hard enough to pick colors for someone when you can see house!)to think about perhaps painting your brick?
Brick paints very well - although once it is painted - it will always have to be - removing paint from brick is nearly impossible.
Try the website &/or CD - I am sure you will find help there.
