good day!

i'm fairly new here, and i was hoping that someone could help me out..

i'm fairly new in using painter x...

i used blender a lot with "just add water" as my brush type... of course, there's supposed to be no colors in it... unfortunately, i accidentally click the buttons on my pen tablet.. which screws up the blender now it leaves gray streaks!!

it's horrible!! imagine unintentionally mixing gray with brown and yellow... aargh!! it irritates me a lot!!

here's the image.. the black circle represents the blender leaving a gray streak.. i can't continue coloring like this! i need help!
