Why are my colors not mixing?

Questions & Answers
1

I am trying to create a system where the player selects a color and clicks on a paint pallet to start mixing colors, the new color can be used to paint the environment. I have created these paintballs the player uses on the pallet but whenever they do the pallet simply changes from white to whatever color has been selected. This would be fine if it didn’t continue with every new color, basically if you try to add red to green it won’t become some mix it will simply become pure green. I am pasting my code down below and would greatly appreciate if anyone has any ideas on what to do to fix this. Id like to note that the preview being referenced in the scripts is simply a painted sphere in the players UI that lets them know what color they have.

Pallet Script

public class Pallet : MonoBehaviour {
    public Color _color;
	// Use this for initialization
	void Start ()
    {
        _color = GetComponent<Renderer>().material.color;
    }

    public void MixPallet(Color color)
    {
        
        Color m_color = ((_color / 2) * (color / 2));

        GetComponent<Renderer>().material.color = m_color;
        Debug.Log(_color + " has been set the color");

    }
}

.

Script that attempts to mix the paints

public class Casting : MonoBehaviour {

    int range = 100;

    public GameObject preview;
    // Use this for initialization
    void Start () {
		
	}
	
	// Update is called once per frame
	void Update ()
    {
        if (Input.GetButtonDown("Fire1"))
        {
            Debug.Log("Clicked");
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

            Vector3 rayOrigin = Camera.main.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0.0f));
            RaycastHit hit;

           
            if (Physics.Raycast(rayOrigin, Camera.main.transform.forward, out hit, range))
            {
                Debug.Log("RayCast");
                PaintBall _color = hit.collider.GetComponent<PaintBall>();

                if (_color)
                {
                    Debug.Log("Paintball has been selected");
                    preview.GetComponent<PaintPreview>().SetColor();
                    preview.GetComponent<Renderer>().material.color = _color.color;
                }

                Pallet _pallet = hit.collider.GetComponent<Pallet>();

                if (_pallet)
                {
                    Debug.Log("Pallet has been selected");
                    preview.GetComponent<PaintPreview>().hasPaint = false;
                    _pallet.MixPallet(preview.GetComponent<Renderer>().material.color);
                }
            }
        } 
    }   

}

For anyone coming across this later I have come up with a solution, I’m not sure why the previous code didn’t work but I do know this code works. I rewrote the Mixing script and have pasted it below for anyone to reference in the future.

public class Pallet : MonoBehaviour
{
    public Color color_A;
    public GameObject Orb;

    void Start()
    {
        color_A = GetComponent<Renderer>().material.color;
        
    }

    
    public void MixPallet(Color color_B)
    {

        if (color_A == Color.white)
        {
            color_A = color_B;
        }
        else
        {
            float r = color_A.r;
            float g = color_A.g;
            float b = color_A.b;
            float r2 = color_B.r;
            float g2 = color_B.g;
            float b2 = color_B.b;

            Color color_C = new Color(0, 0, 0, 1)
            {
                r = ((r + r2) / 2),
                g = ((g + g2) / 2),
                b = ((b + b2) / 2)
            };

            color_A = color_C;
        }
        

        GetComponent<Renderer>().material.color = color_A;

        Orb.GetComponent<Renderer>().material.color = color_A;
        Orb.GetComponent<PaintBall>().color = color_A;
    }

}
