How to relate particle age and color from 'emit particle'

[joe0hara]

Hi, guys

I finished this tutorial (https://www.youtube.com/watch?v=TSFYMnzjYEY&t=818s).
Then I want to relate particle age and color.
I done just particle element but cannot emit particle attached particle element.
Any idea?

Hi!
Did you try to invert the position of the point Attributes and emit particles in the layer tree?
If i do that, i get this result:

is that what you're looking for?

I done just particle element but cannot emit particle attached particle element.
Any idea?

Sorry but i don't understand your problem because on your composition i see that you allready attached an emit particles to your particle system.
Cheers :D!

Thank you for your advice.
I can do it for invert the position of elements.
