Get value for $id from blade section

I am still new to Laravel so I hope someone could help me with the problem I am facing. I have a controller that updates a row in a table depending on the value of the $id. if $id=1, first row is updated, if $id=2, second row is updated, if $id=3, third row is updated, and so on. Is there a way to pass $id to the blade section and from each form(see blade section) assign $id a value?

Controller

public function index()
{         
    return view("theme-changers.index");
}
public function change(Request $request, Response $response, $id)
{         
    $user = ThemeChanger::find($id);
    $user->update(array('color_code' => $request->input('color_code')));
    return view('theme-changers.index', compact('user', 'id'));;
    // $response->withCookie(cookie('color', $input, 999999));
}

Routes

    Route::get('theme-changers', [ThemeChangerController::class, 'index'])->name('theme-  changers.index');
    Route::post('theme-changers/{id}', [ThemeChangerController::class, 'change'])->name('themes.store');

Blade (theme-changer -> index.blade.php)

{{ Form::model($user, array('route' => array('themes.store, $user->id))) }}

                                    <tr class="odd">
                                        <td>
                                            Primary Color
                                        </td>

                                        <td>
                                            <input style="width:100px" name="color_code" type="color" class="form-control form-control-color" id="themechanger1" title="Choose your color">
                                        </td>

                                        <td class=" text-center">
                                            <div>
                                                <button type="submit" class="image__file-upload" id="saveColorChange1">Confirm</button>
                                                <button type="submit" class="image__file-upload" id="cancelColorChange">Cancel</button>
                                            </div>
                                        </td>
                                    </tr>
                                    {{ Form::close() }}

Model (ThemeChanger)

 /**
 * @var string[]
 */
public $fillable = [
        'color_name',
        'color_code',
        'created_at',
        'updated_at',
];

 /**

protected $casts = [
    'color_name' => 'string',
    'color_code' => 'string',
];
