I have some black and white line art that I've drawn in Paint.NET using the paintbrush tool. This is contained on its own layer. On other layers I have color/shading applied. I now have resized the line art layer but now the black lines have now turned to dark-gray. All the instructions I've found for "darken" on this forum are for images. How would I go about darkening the black lines? I've tried with the Contrast adjustment but no luck on making dark gray any darker.
Any thoughts here?
