I guess it’s a two part challenge in fact.
First part is to create these white animated concentric circles on a black background.
I only used Shotcut to create them. No external software.
Second part: After exporting the animation, overlay the resulting clip on any background and change the color of the circles. The circles must stay opaque. Alternate the colors. One of the colors must be black.
(Sorry for the low resolution of this clip, I had to downsize it to meet the 4-meg limit of the forum)
