My brush keeps drawing gray-scales around my lines. I want to remove the gray pixels so I can use the bucket-tool without any problems.

This question came from our site for professional, enthusiast and amateur photographers.

To think the issue other way around, you could also adjust the Tolerance setting of the bucket tool upwards, so it will fill—not only the colour you clicked upon—more of its neighbors. – koiyu Feb 26 '11 at 21:06

You want to use the pencil tool rather than the brush tool to get rid of the grey shades around a line:

Anti-aliasing actually means you do get the slightly fuzzy edges. Aliasing means that either a black or white value is used as an alias for the true shape - the brush is circular but you can't represent a circle with square pixels. Anti-aliasing attempts to prevent the problem of using either black and white to represent an area the curve passes through by representing this area as a shade of grey.
