hahaha im guilty of this before. but yeah colors were a bit too much for me. remember less is more with color correcting. if you can just barely shift the colors one way or another to give a different feel without it being super obvious in some cases its a good job. but just keep working at it and you'll get it, i still am figuring out better methods.
for the slow mo, you should be shooting at 60fps if you want to get smooth natural slow motion. then it depends on what editing software you have. the best way is to conform the 60fps into 24 or 30 fps in most cases. sometimes if you edit in a 60fps timeline like i think eheath does, you can just change the speed of the clip down a little bit without getting too choppy. then just export that 60fps timeline as 24 or 30fps depending on what you like better
