Hello, my color changes very quickly, which I don’t have time to see. I want to make the color change every second.

Ok, so your code has absolutely nothing to do with what you want to achieve.

  1. Use GetComponent once in Awake and store the reference in a field in your class. It’s basic optimization thing, you should always do. Never call GetComponent in Update if you can avoid it.

  2. Use Update instead of FixedUpdate because you are not doing any physics calculations

  3. What is that “while” loop? Currently you are changing the color 400 times in first fixed update and then your code does absolutely nothing.

  4. Changing a color 4 times like that will only display the last color, first three assignments can be thrown away

  5. Below is a code that should do what you need

    private Renderer renderer;

    private void Awake()
    {
    renderer = GetComponent();
    }

    private float timer = 0;
    private const float timeInterval = 1;

    private void Update()
    {
    if(timer >= timeInterval)
    {
    ChangeColor();
    timer = 0;
    }
    else
    {
    timer += Time.DeltaTime;
    }
    }

Edit: for some reason I can’t format the code correctly here, sorry.

You need to change the “while” to “if” because your’e on the FixedUpdate function.
Hope it helps

using Random = UnityEngine.Random;

public class ColorChange : MonoBehaviour
{

private Renderer renderer;

private void Awake()
{
    renderer = GetComponent<Renderer>();
}

private float timer = 0;
private const float timeInterval = 1;

private void Update()
{
    if (timer >= timeInterval)
    {
        GetComponent<Renderer>().material.color = Random.ColorHSV(0f, 1f, 1f, 1f, 0.5f, 1f);
        timer = 0;
    }
    else
    {
        timer += Time.deltaTime;
    }
}

}

This code is working.
Thanks @Casiell!!
