I had some short animations made for intro and outros for YouTube, Instagram, and Facebook. I used a designer on www.Fiverr.com who turned these around in 24 hours and made any changes I wanted as well all for $15. I received 10 videos in 4K resolution. The 11th short was added as a bonus because they were not able to make a change I wanted. I highly recommend checking out Xar Studio on Fiverr here: https://www.fiverr.com/xarstudio?source=order_page_summary_seller_link
I like the basic ones with the same color scheme like you mentioned. But really it was about polling about 50 people and gauging what they liked. I can like bad ideas all day long lol.
