For a given video length, there will be some youtube video urls without roman numerals, and with low digit sum, and atomic number.
I first search this on Google
"0:00 / mm:ss" site:youtube.com
Where mm:ss is the desired length. Then I used some Javascript to scrape the results, finding only youtube urls without roman numbers, and print them out sorted by digit sum and atomic number
I've done it a few times, never had a situation where there was no suitable url
As for the color hex, if it's not suitable, you can regenerate it
