I was excited when i first found out about the theme editor as i have some eyesight problems that i assumed the editor would help me with. I was really annoyed when something essential for people with vision problems was just for the platinum users, i can only afford the artist version.
I don't think anyone at Cakewalk really thought of the theme editor as something for people with vision problems although as an application, that makes sense. The motivation for the theme editor was all the people who had requested more color customization options.
When/if I finish my theme it might be what you need. Although not intended specifically for those with vision problems, it is intended to be highly visible from the rear of a room when I'm doing seminars. Meanwhile, if you could specify what would make a theme vision-friendly, maybe one of the graphic geniuses here could whip something up.
