Need Help=Ink Refill Kit

This is my first time at using a ink refill kit. I followed the directions, and even check out you tube videos. I kind of over filled the Blue, and spent 2 hours cleaning the excess off the cartridge. Now when I print something Yellow it prints Green, and Green becomes Brown when printed. Is it because I over filled the Blue or did I put the wrong colors in the wrong holes? At first it printed something Yellow blue, but then started going from Blue to Green, and right now it is staying Green.
