whats the difference with these two saws?

Hi new to this site, very informative!
I am buying a climbing saw a husky 335xpt ( before you tell me not too I only use chainsaws in the winter months and so don`t use them very much)
can anyone tell me why in the pics the oil and fuel filler caps are different colours, does this suggest one is newer than the other or something else?

Not, sure if it means anything, some Huskies come with light gray caps as well.
