Lower unit oil

[steplift20]

Today I started my boat and after a few times I cranked her she finally started Happy about hat but I also changed the lower unit oil, the last time I changed it I noticed the color was two differant shades of green Dark and a light color so today I changed it and it's two differant shades of green dark like the oil and light shade I used quick silver lower unit oit I was wondering if that is good ? When you change yours is the color all the same color? If not then I might have a seal that went bad but it's not the milky color the would indicate a bad seal Thanks for any comebacks
