I'm new to the world of encoding and I have done a few videos using HandBrake but it seems like the color is always off.
I've exported a few screenshots between the source and the encoded but it kind of shows a greenish tint and I am not sure what settings could help fix the color issue.
If someone could help me with this, that would be great!

You probably have a display problem, not an encoding problem. How did you produce the two images?
Not sure if I'm allowed to bump this thread but I apologize in advance if that's the case.
Not sure if I'm allowed to bump this thread but..Please try not to "bump" your topic.
Replying to your own topic to get it to the top is annoying. Try to have some patience, this is a bulletin board, not IRC. It may take some time (e.g., one or two days) before someone can answer your query or question.
picture link doesn't work for me,...
Instead of pictures which might not be taken properly, small video samples are usually better, since they allow others to decode the content themselves and easily spot some of the usual problems.
here are a few of the typical reasons for color differences:
- missing VUI flags which inform the decoder about the color (especially when resizing/cropping the content)
- decoder that doesn't read or respect the color infos
- some post processing which does change the color
- some filtering which did a YUV<>RGB conversion during reencoding which didn't respect the color matrix
- problem with video renderer (especially when videos are opened in parallel)

AviDemux. Set Video Output and Audio Output to Copy. Set the Output Format to the same as your input (MP4, MKV, AVI, etc.). Use the Mark-in (A) and Mark-Out (B) tools to select a small portion of the video that shows the problem. Save the clip.
Encode the clip with Handbrake as you did before. Verify you have the same color problem.
Upload the two clips.
Doh,.. no clue why I read this as 'hat's the best way to compare the video samples?' *gig*users currently on my ignore list: deadrats, Stears555
If nobody could see your pictures you will receive no help, your link is broken to me.

I did go ahead and encode it anyway to check the colors and the colors do seem a bit off. I think it looks darker? Please mute the audio so it doesn't kill ears though.
The links aren't working for me. It says I need a decryption key.
I'm seeing essentially the same colors. Even interleaving the two videos and stepping through frame by frame. I can no longer see the images in your first post, but as I recall the differences weren't as large as a rec.601 vs rec.709 error, or a PC levels vs. video levels error. I suspect the differences you are seeing are the way your computer is displaying 10 bit AVC vs. 8 bit AVC. Do you have a particular frame where you see the biggest differences? I'll upload images from my computer for you to compare.

Also, is there something I can do about the jumbled audio from AviDemux?

Nearly identical aside from encoding artifacts.
