Different color milk ?

The lighter one is the one you feed and pump more on and the darker one you pump and feed less on usually means that there’s more colostrum in that one

nah you stop producing colostrum once your milk comes in all the way. the darker one just looks like it may have a lesser amount of what's called foremilk, so it's got a higher fat content. totally and perfectly normal. milk can be all sorts of colors for several reasons.

Milk can be any tinge of pink blue green yellow and be all normal. The pink is usually from cracked nipples and a tiny bit of blood fell in there but it’s edible and won’t hurt baby at all. If we are sick we produce more antibodies and that might turn it a tinge of blue

@Kellie correct! or a tinge of yellow
