Get particle gradient color

I see how to set a particle's color based on a gradient (e.g. this & this) but I can't find anything on how to get the color.

I have a particle system with the start color set to random with a gradient. I've tried...

Color myColor = myParticleSystem.main.startColor.color

... but it always returns black, regardless of the gradient colors.

I don't see anything in the docs or forums about how to actually get the color that was randomly chosen.

Using Unity 2017.3. Thanks.

At the moment, we can't read the MinMaxCurve from scripts, as per here: https://blogs.unity3d.com/2016/04/20/particle-system-modules-faq/ (scroll down to the Easing the Pain section).

However, your code returns not a MinMaxCurve, but the Start Color of type Color that you can set via inspector or via script.

For example, if you create a Particle System game object in a scene, and you attach to it this simple script:

using UnityEngine;

public class ParticlesTest : MonoBehaviour {

    ParticleSystem myParticleSystem;
    public Color myColor;

    private void Awake() {
        myParticleSystem = GetComponent<ParticleSystem>();      
    }

    private void Update() {
        myColor = myParticleSystem.main.startColor.color;
    }
}

you can see that myColor changes when you change the Start Color value of the Particle System in Play mode.
