Update Inner Child Inside Child Inside Parent In laravel 10

Hi , i built a small ecommerce using laravel and i am using React for front-end my question about the product store and update, every thing is work but there some problems in, i am creating the product using the store method :

  public function store(StoreProductRequest $request)
    {
        $product = new Product();
        $request->validated();

        $productCreated = $product->create([
            'title_en' => $request->title_en,
            'title_ar' => $request->title_ar,
            'description_en' => $request->description_en,
            'description_ar' => $request->description_ar,
            'price' => $request->price,
            'discount' => $request->discount,
            'price_suadia' => $request->price_suadia,
            'discount_suadia' => $request->discount_suadia,
            'price_emarat' => $request->price_emarat,
            'discount_emarat' => $request->discount_emarat,
            'price_dollar' => $request->price_dollar,
            'discount_dollar' => $request->discount_dollar,
            'coming_soon' => $request->coming_soon,
        ]);


        if ($request->colors) {
            foreach ($request->colors as $colorData) {
                $color = new ProductColor();
                $color->name_ar = $colorData['name_ar'];
                $color->name_en = $colorData['name_en'];
                $color->color = $colorData['color'];
                $color->quantity = $colorData['quantity'];
                $color->product_id = $productCreated->id;

                $file = $colorData['image'];
                if (filter_var($file, FILTER_VALIDATE_URL)) {
                    $color->url = $file;
                } else {
                    $filename = date('YmdHis')  . '.' . $file->getClientOriginalExtension();
                    $path = 'images';
                    $file->move($path, $filename);
                    $file = url('/') . '/images/' . $filename;
                    $color->url =  $file;
                }

                $color->save();
                if (isset($colorData['images'])) {
                    $files = $colorData['images'];
                    $i = 0;
                    foreach ($files as $file) {
                        $i = $i + 1;
                        $image = new ProductImage();
                        $image->product_color_id = $color->id;
                        if (filter_var($file, FILTER_VALIDATE_URL)) {
                            $image->url = $file;
                        } else {
                            $filename = date('YmdHis') . $i . '.' . $file->getClientOriginalExtension();
                            $path = 'images';
                            $file->move($path, $filename);
                            $image->url = url('/') . '/images/' . $filename;
                        }
                        $image->save();
                    }
                }
            }
        } else {
            return response()->json([
                'error' => 'يا أخي على الاقل لون واحد'
            ]);;
        }

        return $productCreated;
    }

the product has all this columns, but has color child which is has a child also called images every color has this data:

$color = new ProductColor();
                $color->name_ar = $colorData['name_ar'];
                $color->name_en = $colorData['name_en'];
                $color->color = $colorData['color'];
                $color->quantity = $colorData['quantity'];
                $color->product_id = $productCreated->id;

                $file = $colorData['image'];
                if (filter_var($file, FILTER_VALIDATE_URL)) {
                    $color->url = $file;
                } else {
                    $filename = date('YmdHis')  . '.' . $file->getClientOriginalExtension();
                    $path = 'images';
                    $file->move($path, $filename);
                    $file = url('/') . '/images/' . $filename;
                    $color->url =  $file;
                }

and the color also has this :

                $color->save();
                if (isset($colorData['images'])) {
                    $files = $colorData['images'];
                    $i = 0;
                    foreach ($files as $file) {
                        $i = $i + 1;
                        $image = new ProductImage();
                        $image->product_color_id = $color->id;
                        if (filter_var($file, FILTER_VALIDATE_URL)) {
                            $image->url = $file;
                        } else {
                            $filename = date('YmdHis') . $i . '.' . $file->getClientOriginalExtension();
                            $path = 'images';
                            $file->move($path, $filename);
                            $image->url = url('/') . '/images/' . $filename;
                        }
                        $image->save();
                    }
                }

everything works fine but the problem when i update the product with its images:

 public function update(StoreProductRequest $request, $id)
    {
        $product = Product::findOrFail($id);
        $request->validated();

        $product->update([
            'title_en' => $request->title_en,
            'title_ar' => $request->title_ar,
            'description_en' => $request->description_en,
            'description_ar' => $request->description_ar,
            'price' => $request->price,
            'discount' => $request->discount,

            'price_suadia' => $request->price_suadia,
            'discount_suadia' => $request->discount_suadia,
            'price_emarat' => $request->price_emarat,
            'discount_emarat' => $request->discount_emarat,
            'price_dollar' => $request->price_dollar,
            'discount_dollar' => $request->discount_dollar,
            'coming_soon' => $request->coming_soon
        ]);

        // Update colors and images
        $product->colors()->delete();

        if ($request->colors) {
            foreach ($request->colors as $colorData) {
                $color = new ProductColor();
                $color->name_ar = $colorData['name_ar'];
                $color->name_en = $colorData['name_en'];
                $color->color = $colorData['color'];
                $color->quantity = $colorData['quantity'];
                $color->product_id = $product->id;

                // Handle color image - URL or file
                if (isset($colorData['image'])) {
                    $image = $colorData['image'];
                    if (filter_var($image, FILTER_VALIDATE_URL)) {
                        $color->url = $image;
                    } else {
                        $filename = date('YmdHis') . '.' . $image->getClientOriginalExtension();
                        $path = 'images';
                        $image->move($path, $filename);
                        $color->url = url('/') . '/images/' . $filename;
                    }
                }

                $color->save();

                // Handle additional images - URLs or files
                if (isset($colorData['images'])) {
                    foreach ($colorData['images'] as $image) {
                        $productImage = new ProductImage();
                        $productImage->product_color_id = $color->id;
                        if (filter_var($image, FILTER_VALIDATE_URL)) {
                            $productImage->url = $image;
                        } else {
                            $filename = date('YmdHis') . '_' . uniqid() . '.' . $image->getClientOriginalExtension();
                            $path = 'images';
                            $image->move($path, $filename);
                            $productImage->url = url('/') . '/images/' . $filename;
                        }
                        $productImage->save();
                    }
                }
            }
        } else {
            return response()->json([
                'error' => 'يا أخي على الأقل لون واحد'
            ]);
        }
        return response()->json(['data' =>  'Product Updated Succesfully']);
    }

as you can see i am deleting the colors and re create it , the problem now : when the user update the product everything works fine , except for images of the color, if he upload five images it become 3 images in the database, and maybe 2 i don't know why and there is another problem, in my way everytime the product updates , it is create a new color is that problem for perfomance ? so does anyone know why first problem happens ?
