1. A multi-fluid kit for three-dimensional printing, comprising:
a low tint fusing agent including an electromagnetic radiation absorber in a liquid vehicle, wherein the electromagnetic radiation absorber absorbs radiation energy and converts the radiation energy to heat; and
a coloring agent consisting of:
from about 2 wt % to about 4 wt % of a magenta rhodamine dye;
from about 4 wt % to about 16 wt % of a fluorescence quenching iodide salt, wherein the fluorescence quenching iodide salt is included in molar excess relative to the magenta rhodamine dye;
an organic co-solvent; and
a balance of water.
