user6256: I'm creating some basic advice videos, which are explicitly intended to be produced quickly.  I'm using a low-grade webcam to do video captures and don't have any special lighting.  I don't need my videos to be beautiful, and don't want to put too much effort into correcting them, however, I am annoyed by my 'digital jaundice'.
I'm looking for a simple and free tool which can help me remove the yellow shade.  I don't need power, I'm not willing to pay anything, and I'm not willing to put in too much effort into correcting the color before I give up and post videos as a lost Simpson character :).  It seems like there should exist a simple open source tool for exactly this use case.  Can anyone recommend a free tool?
I'm sorry if this is a repeat question.  I feel like I should be able to figure this out on my own without asking, but I've honestly spent time googling and looked through this site and haven't been able to find the information, perhaps because on this site everyone has way more domain knowledge, the one question i did find that seemed to address this question the answer went over my head lol.
Edit:  It turns out I didn't need any tool.  Youtube has built in an ability to adjust your lighting after uploading a video.  It's not very fancy, but it's enough for my needs, simple to use, and most of all it's fast because it utilizes 'the cloud'.  Still, thank you for your feedback

user6210: Blender's compositor will do exactly what you want, just enter the compositor (on the right of the help button on the menu, change default to compositor) check nodes and backdrop, add your video as input (press shift+A on the the compositing window) you can remove the render node since you are not using 3D, press shift+CTRL+left_mouse_button on the input node and your movie will be displayed as background, now you can add color nodes to correct the colors of your image. Link nodes and you will see the color correction in the background image. When you are happy match the number of frames to those of your video and render the whole thing. 

user2836: The cheapest tool is to use a desk lamp and light the scene better to begin with and use the white balance setting in the webcam software itself.  It's a lot harder after the fact (if sufficient detail is even saved in the video to fix it at all).  
You could also try DaVinci Resolve Lite, it's a professional color grading and correction package that also happens to be completely free, but the much better solution is to light and shoot correctly rather than trying to fix crappy footage in post.
