My bad, I just mixed some yellow and magenta and it does give an orange to brown so it is still the yellow leaking.
You said you stood it up overnight and nothing came out? There is still a leak. You might have nicked the edge of the hole opening
Take some of the blue rubber stuff. Back off the screw two turns. Stuff it in below the screws and retighten the screw. You want to seal it AIRTIGHT. If all else fails. Seal it with a hot melt glue gun from the dollar store or a dab of silicone to prove the problem is an airleak.
