hi everyone

i dont know if this the right place to ask so a big sorry up front if its in the wrong place  :lol:

i need to change the ink color on a old u.s map thats come from a book from red to black,the reason is im going to frame it and the red is hard to see,

i should say the maps worthless so im not bothered about changing the color of it but it would look so much better in black

iv tried so many things using the pages but no luck...  :cry:
does anyone know if there a chemical out there that will do it for me
any help would be great

thanks
den

Trace over it in fine point sharpie?      Dyes are typically very, very complex chemical structures - I doubt there's going to be a way to chemically change the red dye into black dye.

i believe the ink used is "red lead pigment mixed with linseed oil"
this there no chemicals that could turn the red lead pigment black
