The term for 'black and white' is
shirokuro -- 白黒 white and black
Momo iro literally means 'peach color' as in the color of the fruit, but the color this refers to in Japanese is not peach but pink.
Green fruits and vegetables (such as green apples) are refered to as Ao (blue) not
Midori iro (green). Ao also means 'young' or 'unripe'. The green light on a traffic signal is not called Midori iro either, but Ao.
Japanese children tend to say that tigers are yellow and black, not orange and black.
