Yellow spots - called bruises - are watermelons that come into direct contact with the ground. Ripe watermelons often have yellow spots or even orange-yellow, not white.
The brown spots on the watermelon skin are caused by bees that sting on pollen many times. It means more pollination, the sweeter the watermelon.
Many people do not know that farmers also distinguish watermelons according to varieties. For example: " male " watermelon is bigger, has an elongated shape and lots of water, while a " female " watermelon is round and very sweet.
