CakePHP：具有一个结果的随机查询，排除两个值

Question

I try to exclude two values on a random query, but it gets ignored. Maybe one of you can enlighten me. This is my code:

$random = $this->Gerde
    ->find('all', [
        'conditions' => [
            'OR' => [
                'NOT' => [
                    ['employees' => 'BLUE'],
                    ['employees' => 'RED']
                ]
            ]
        ]
    ])
    ->order('rand()')
    ->first();

I get my single random result but red and blue employees appear anyway. Does my logic suck? Thanks in advance.

GregSchmidts answer was the right one. My code looks like this now and works like a charme:

$random = $this->Gerde->find('all', ['conditions' => ['employees NOT IN' => ['BLUE','RED'] ] ])
                         ->order('rand()')
                         ->first();
