I don’t usually work with real "blue"prints. I often import drawings as black and while, and then knock out the background using a selective color.
that’s a cool color 
i’ve tweaked all my colors to ones used in the solarized color scheme
“Solarized scheme”?
Also, should there be a thread where we can all swap optionsexport files?
I think you’re confusing “blueprints”, with “blue lines”.
Ah.
I just use a set of 20 contrasting colors I got from an information design blog. This is prettier.

my first and only “blueprint” machine was one that used a chemical other than ammonia and printed blue lines on a white background. No odor and an eminently readable print!
I used to like that ammonia smell!
Yeah…it’ll keep your sinuses clean!
Neat! Could you post a picture of how everything looks with that setup?
My colors:
My color picker plug-in custom colors, chosen for high contrast working on a dark background:
Eyedropper selection would be handy so you could like pictureframe in an image with the swatches you want to use and pick off them.
WIP has eyedropper already.
looking at the image there doesn’t seem to be that much of a difference but to me it’s softer on my eyes.
That looks pretty sharp actually. Nice job! I might have to give that a try.
