title: Displaying blue with SDL2 and OpenGL
body: <p>The title of this question is a bit misleading because I know how to display color thanks to <a href="http://headerphile.com/sdl2/opengl-part-1-sdl-opengl-awesome/" rel="nofollow noreferrer">this</a> tutorial. After getting it to work I decided to use it so I gutted one of my old bits of code that was a test of SDL2 when I first started using SDL2, and replaced all the renderer stuff and some other stuff, and replaced it with an OpenGL context and tried to get it to display blue, but with no luck it just displayed a black screen. Not sure what the exact issue is. <a href="https://gist.github.com/TheAceShinigami/f0e525914013f39836df33d29ded1a67" rel="nofollow noreferrer">here</a> is a gist </p>
  
  <p>P.S. if can think of a better title I'm all ears :)</p>
