It’s clearly an animated mode of a eigen value analysis. Therefore it’s “displacements” that a structure experience when subject to a vibration at it’s natural frequency. However the actual maginitude of these displacements have no meaning it is only to represent type of deformation shape one would see. If it were stress or strain you would see colors close to the base (support) of the beam.
In the color indicating distance moved or stress? If the latter I would except it to be more towards the middle of the beam?

Clearly… I mean everyone should know an eigen value analysis

I added clearly as a joke :)
Clearly it was a joke :-p
It probably is strain. Not stress
