Excuse the old art (circa 2013-2014), but this is why color correction is important. Color can do so much to the mood of an animation or video.
I decided to take a look at my old animation project I uploaded onto YouTube in 2014 and realized there are a lot of issues with the overall color. I went back and messed with the settings and created something that I feel fits the overall mood of the piece better.
Doing this makes me want to revisit animation more and more.
