Prussian Blue, You know--for Blueprints : )

Rhino for Windows
#1

I usually make layers for 2D blue curves blue, for blueprints. Lately, I’ve taken to using a variation of Prussian Blue, which was involved with traditional Cyanotype blueprint making.

Wikipedia states that the RGB color coordinates are: 0, 49, 83
Working with Rhino3d’s default color scheme, I use: 0, 76, 128
…which is the same shade but with a brighter. Only 2 values need to be typed.

It might be handy for the internet/Photoshop crowd, if people could type in a hex RGB value into the Rhino color coordinate box.

Cool, but why set it as an object color rather than a background color if what you’re into is blueprints?

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.

“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!

In deed, hex would be very welcome!

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.
