Black and Yellow Bus

I described to artificial intelligence what a bus should look like in my opinion and got it to draw the bus for me. I think a bus would look cool if it was black and covered in yellow polka dots. In my head it looks cool but when the ai drew it, it looked lame so I asked it to reverse the colours. 

In my head it looks better the other way. The black paint would hide blemishes like UV damage to the paint and small dents and the yellow dots would make the bus easy to see, even if some of the passengers were partially blind. The interior of the bus would look pink and have pink filtered lights. At night you would would see a spotted bus with pink light sweeping out of the windows. .

I think the problem here is there isn't enough contrast. In my head the bus would be very black and the dots would be smaller and more numerous.
