25 drops X2 Brown in 8 ozs?!?I'm thinking You might try using something to make sure the Brown pigment powder isn't hard-packed in the bottom of the bottle.I have Caney Creek non-X2 Brown and X2 Brown. My non-X2 Brown doesn't take much to get up there...the X2 Brown is potent.
Roger dat, HT.Can You post a pic of where the color's at?
If you have some straight, non-fluorescent green, try a couple drops to see where that goes.
