-#### Introduction
+### Introduction
 
 Color Assistant is a tiny Windows software that contains two convenient tools to help people with color vision deficiency (color blind) to read color-labeled data graphs. The two tools are:  
+  
 1. Screen color flasher: click on any point of the screen and the same color appeared anywhere on the screen will flash.  
 2. Screen color filter: add a color filter to the whole screen to discriminate some confusing color pairs, including red to brown, blue to purple, and green to orange (for people with the most common color blind types).  
+  
 The first tool may even be helpful to people with normal vision for reading figures with too complicated colors.

 Color Assistant is in open beta, and any suggestion about how it could better help people is welcome!
