animation of particle color

I animate the particle color from red to green to blue but the color change not depending of the time but depending of the age of that normal? and how to change the color but not depebding of the age?

Sadly, this is the current state of particles. As far as I know, the only way to change a particle’s colour based on time is through use of the compositor.

It s a more realisic behavior but. i m gonna try with a light and white particle
