Toning a cyanotype involves two basic steps: a bleach phase, and a toning phase. Every toner I know of contains some type of tannin in it: tannin chemically binds to the iron in the emulsion and changes the color.

How do Anthotypes work?
An anthotype is an image created using photosensitive material from plants.

The color remains in the shadowed parts.

How do you get color back from a cyanotype?
Cyanotypes won’t achieve full color richness until they have dried for about 24 hours. Or, you can get immediate results by dipping the print in a bath of water mixed with a small amount of hydrogen peroxide. This will bring the print to immediate color richness. Rinse with fresh water and move on to the bleaching phase.
