Jared Smith has provided a new tool based on many color checkers available that offers the ability to lighten and darken your color combinations slightly to find acceptable contrast levels. This new tool is at https://webaim.org/resources/contrastchecker/
Code-it Software Solutions has been a player in the development of Assistive Technology (A-Tech) software since 1997. They were the first to release "talking" web browsers (named "Web Talkster" & "Web Speakster") to aid children with ADD, or folks with poor eye sight, to enjoy the web. They offered their array of Windows XP or Vista platform software stuff all wrapped up in one package type application in the hopes that you'd benefit in some way from it's use.
You didn't have to have special needs to enjoy this software! Anyone (particularly kids) that enjoys text 2 speech software will get good use from the many applications it offers! This software is entirely freeware, no adware and / or spyware. You could use it free forever. The software included Text 2 Speech Stuff…Speaking Note Pad, Text 2 Audio, Text Talkster, Web Talkster; Misc Stuff…Audio Recorder/ real time, Audio CD Writer, Data CD Writer, Magnifier, Sign Talkster; and Fun Stuff…Guess the Number Game, Picture Taker, Peedy the Jokester, and Song Gallery.
The Code-it Software Solutions website closed down and discontinued distribution of all their software on 01.01.2019
