Recolored Sprite out of Texture2D does not have same size as before

Hey everybody. I have a small question:
So I have this Script that searches for a color in a sprite through converting it into a Texture2D.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class ColorChanger : MonoBehaviour
{
    public Color getColor;
    public Color newColor;
    public SpriteRenderer renderer;
    public Sprite size;

    // Update is called once per frame
    void Update()
    {
        CopyTexture2D(renderer.sprite.texture);
    }

    //CopiedTexture is the original Texture  which you want to copy.
    public void CopyTexture2D(Texture2D copiedTexture)
    {
        //Create a new Texture2D, which will be the copy.
        Texture2D texture = new Texture2D(copiedTexture.width, copiedTexture.height);
        texture.filterMode = FilterMode.Point;
        texture.wrapMode = TextureWrapMode.Clamp;

        int y = 0;
        while (y < texture.height)
        {
            int x = 0;
            while (x < texture.width)
            {
                if(copiedTexture.GetPixel(x,y) == getColor)
                {
                    Debug.Log("color found");
                    texture.SetPixel(x, y, newColor);
                }
                else
                {
                texture.SetPixel(x, y, copiedTexture.GetPixel(x,y));
                }
                ++x;
            }
            ++y;
        }

        texture.Apply();
 
        Rect spriteRect = new Rect(0, 0, size.texture.width, size.texture.height);
        renderer.sprite = Sprite.Create(texture, spriteRect, new Vector2(0.5f, 0.5f));
    }
}

I use the Sprite “size” as an example for the sprite size.

The color-changing works and I get a recolored Sprite back into my SpriteRenderer. But that new Sprite is bigger than my original, even though I use that stuff with “size”.

Does anybody know how I can scale my Sprite as big as before? (128x128px, if that´s important.

Thanks in advance

check this link, the issue appears to be related to mipStripping

Thank you!
So I need to enable the mipStripping before using the height and width?

when you do sprite create you are not putting the pixels per unit, so you should add an extra parameter on sprite create to your original pixels per unit
