What color do you prefer for the farts on my comic? (Patreon)

Well guys, I'm drawing the gassy stuff on my A&TESC kinky edition comic and I don't know what color use for farts.

I uploaded here two pictures as the examples of the different gas colors that I'm interested, one is a little yellow and other is more brown

Vote! what color do you prefer? remember that Urebura tier votes counts as x2!
