"Li'l Decor" Christmas tree ornaments...another YouTube...but what's with the colour?

Hi!

This was uploaded a few days ago. Sorry for the delay, we were trying to figure out why the colour loaded differently than the first two. Don't ask me, I'm not a techie.
Looks the same when we open the file to modify, but looks different when we view on YouTube! Can't figure it out, maybe if we do, we'll update the upload. Still really happy with the video though, as it completes the series!
Check it out! Oh, and if you have any idea what might have gone wrong with my colour, please let me know!
