solid_color_thumbnail
An image whose thumbnail is simply a solid color rectangle.
This can happen in a few situations:
* An animated image or video whose first frame is solid black or white, which causes the thumbnail to be solid black or white too.
* An image with a transparent background that was intended to be viewed over a black background, but the transparency was converted to white for the thumbnail.
* A thumbnail surprise (a two-frame non-looping animation where the first frame is intentionally blank).
