Light Color Fake?

I have seen dark yellow masteron that was good and was hard to draw up. But this time I came across some Very light colored masteron almost the color of water but a little more tanned. The light one is very easy to draw up unlike the dark one that is very hard to draw up.

The light one and the dark one have the same manufacture date.

Does this signify that the light colored one is a fake?

Was told it has to do with the way it was filtered could this be true?
