How to change color with particle age

[Fabrice]

I'd like the particle to be - let's say - red at birth
and blue at the end of their life.
How to achieve that please ?

(I cant get "Instances material" to work)
Cheers

Have you looked at the tyFlow_UVWGradient_001 example file?

I just opened it, thanks.
It looks like it's a solution...but the custom property looks quite complicated!
I'll try to understand that and to apply it to my scenes.
