I'm looking for red and green colors which are still really distinct when printed as a grayscale image.
My current color values (224,133,0 and 168,181,10) are really industuingable on paper.
Any variation in brightness/saturation of colors will be distinguishable in greyscale. I.E. a bright red and a darker green. Or a dark red/burgundy and a bright green.
But really the best red green in greyscale is this one....
Required, but never shown
