Define Brush Preset Colors Inverted

[Lillian23127095nzap]

I am trying to create a blended dot from black to white. When I try to save it using define brush preset the colors always come out inverted. It is probably because of something in settings, but I cannot find where or how to fix it. Been trying for over an hour now. Please tell me what I should do to fix this.
