there are more that 4 types of pumpkin ,but the most popular 4 are orange, stripped, yellow and green
It just turns orange as it ripens, which also shows when the pumpkin is ready to be picked. There isn't really a reason why vegetables/fruits turn colors. It is just the natural color they turn when they ripen.
A pumpkin comes in quite a number of colours. Most pumpkins I see is mostly orange and some might be brownish or a little green too! You can find more colours of the pumpkin and the Wikipedia! Have fun! Thanks!
