Make Particle System Grass inherit color from Ground?

Hi there! I am trying to create some stylized grass for an animation. I came across a resource that does it with Geometry nodes, but performance wise it is horrendous since I need to realize instances for this to work when I apply wind to it.

Is there a way to make a shader and copy the gradient from the ground(or even make a big gradient map and distribute it over all of the instances) so that I can achieve a similar effect? I tried N methods but none of them seemed to work. The grass I want to use is a Hair Particle set to Object.


Thank you!

Use the Render Setting inside the Hair Particle System…
