Here is a free Windows computer program that you can use to help you pick your colors. Although it is not perfect, it can make things easier than standing in the paint store and looking at all the color choices all day. Once you get the color you want you can view it on screen and print it to the size you want.
Please use the help file (F1) to find out how to get the best results. I hope it makes picking your colors easier.
I have run the latest virus and malware scan on the file prior to uploading it to my site. I recommend that you scan it again after downloading for your protection. If you have any questions, please let me know.
You may freely give it away to anyone who you think will benefit from its use.
