Color.yellow

Description

Yellow. RGBA is (1, 0.92, 0.016, 1), but the color is nice to look at!

//Attach this script to a GameObject with a Renderer (go to Create>3D Object and select one of the first 6 options to create a GameObject with a Renderer automatically attached).
//This script changes the Color of your GameObject’s Material when your mouse hovers over it in Play Mode.

using UnityEngine;

public class Example : MonoBehaviour
{
    Renderer m_Renderer;

    void Start()
    {
        //Fetch the Renderer component of the GameObject
        m_Renderer = GetComponent<Renderer>();
    }

    //Run your mouse over the GameObject to change the Renderer's material color to yellow
    void OnMouseOver()
    {
        m_Renderer.material.color = Color.yellow;
    }

    //Change the Material's Color back to white when the mouse exits the GameObject
    void OnMouseExit()
    {
        m_Renderer.material.color = Color.white;
    }
}
