Linux mint cinnamon for the partialy blind

[DanaRoch]

I am starting a project to create a desktop environment for people with severely limited vision , by adapting Linux mint cinnamon. I have managed to create some useful colour themes with 00max. However there are a few bugs as it is not up to date with Zara. AS I am very new to coding in Linux. Is there a guide to creating a theme with Cinnamon spices?
Also , once I have several themes I need to develop a very simple way for partially sighted people to choose a theme. Once completed it would be a mint os specifically for the almost blind. There is technology out there already and I have tried lots of it. But I can tell you it often falls short of the mark! Also a lot of it is very expensive. Ideally a menu integrated into the system allowing to make basic colour choices for fonts and system menu backgrounds would be best.
Any advice or assistance would be greatly appreciated.

The easiest to learn to create a theme is grab something like the default theme and learn how to build and modify. Then start experimenting. It's really not the complex.
