I'm trying to use the color ramp to change the particle colors over time, but i realize that even if the object I assigned as a particle changes its color the particle has a fixed gradient that is not dependant on the material of this particle I used.
Here are all the node combinations I tried to use
And i also tried the nodes suggested on these answers: How do I get particles to change color over time?
I really don't know what I'm doing wrong, I've to test it with a mix node combining an emission node and a transparency node to see if it works but the particle system appears to be semi independent from the particle object material.
Here's my blender file, but it's basically what I show here:
