Paint.Net darken selected pixels?

Question

how do i darken the selected pixels? (eg move them closer to black).

I have some thin grey lines in a picture but they are not visible when i print out the image. I can select them using the magic wand but i dont know how to make them darker..

Solution

There are lots of ways to do this. One option is to adjust the Brightness/Contrast or Hue/Saturation (look under "Adjustments".) Another is to zoom in so you are close enough to click accurately on the one-pixel-wide line and use the paint bucket tool with a darker color.
