Yes! and that’s what the material is doing.
The object info node’s random socket will output a random value between 0 and 1 for each object, which corresponds to a position on the color ramp, giving a different color per object.
The more colors on the color ramp, the more random it will look.
The current setup of the color ramp is mostly blue and orange.
Try moving the flags on the color ramp, add more and change the colors.
