New description:

 Try converting the attached animated PNG file, spiral.png, into a GIF
 animation with the command
 {{{
 ffmpeg -i spiral.png spiral.gif
 }}}
 Notice that in the resulting file, spiral.gif (also attached), colors are
 distorted: almost all the curves are in yellow.

 Reported FFMpeg version: N-118325-gea381285e7-20250119,
 OS: Windows 10 Home.
