It is because you are using the brush tool with a very small, 1 pixel size. The brush tool 'surrounds' the edge of the brush with anti-aliased, semi-transparent pixels. These make the painted shape look smoother. Only 1 pixel then all semi transparent Wink

If you need to paint-in individual solid pixels use the pencil tool which does not use anti-aliasing.

Your image is in indexed color mode and can only use colours that are assigned to the image colormap. (see: https://en.wikipedia.org/wiki/Indexed_color)

Change the mode to RGB: Use menu Image -> Mode -> RGB
