Pretty much, I would say that both of the Biscuits are clear, but it does lean towards the "tinge" of yellow since you planted the idea in my head

So it's not exactly like water clear, but darn close.
I only buy from RTS when I can't find the flavor I want anywhere else.
They re-bottle a lot of their flavors since they buy in barrels, and I have heard a lot of complaints from vapers about how the flavor can vary between bottles, or buying times.
It won't have a strong smell .. actually it's a delicate flavor on the soft side ... but kicks in when mixed.
The easiest way to test any flavor, is to just make a 2ml test of it solo. That way you can test the strength of the flavor, and see if it's any good to start with.
I have a lot of flavors that I start out testing a 1%, .. you can always add a drop or two to the test bottle until you can taste it.
If I can't taste it solo, I sure won't taste it in a recipe. And ... if I have to use a ton of flavoring, it better taste good solo, because I won't mix with it because of the high % it requires, unless it go's with another flavor that is super strong. I like to keep my flavoring under 20% total
I have also had to buy the same flavor from about 5 different company's before finding one my taste buds liked. Everyone makes Strawberry taste different
But Biscuit (either one) makes the best "bakery, or pastry" type of flavor that I have tried.
And how does the saying go .... I've kissed a lot of frogs

Just play with it, or any flavor, and start low,.. you can always add a drop or two.
