10 thumbnails created

I want to monetize on YouTube and was told that having better thumbnails and video titles that summarize thumbnail titles can help drive more people to watch your videos. I was also told that keeping a somewhat consistent color scheme is very important to so that it is easier for people to recognize you videos.
Can you create some great new thumbnails for about ten videos that I have already published? Here is a sample of the color scheme that I want . also with titles that will draw more viewers as well Now that color purple is just the basic color what I am hoping Assad that you can create 10 different thumbnails to my highest viewed videos. Here is the link so that you can look at the views. https://www.youtube.com/@ronaldhendersonakathefitne8806/videos
