First Claim
1. A microfluidic pen for selectivly writing lines of different colors, comprising:
- a) means defining a colorant mixing chamber and a writing tip in communication with the colorant mixing chamber;
b) a plurality of colorant reservoirs disposed in the pen and which contain different colorants;
c) pumping means selectively effective to deliver colorant in selected amounts from the colorant reservoirs to the colorant mixing chamber wherein the colorants are mixed to provide a colorant of the desired color;
d) color selector means responsive to a user selecting the desired line colors and for actuating the pumping means so as to cause the desired amount of colorants to be delivered to the colorant mixing chamber where the writing tip can write a line of the desired line colors.

Abstract
A microfluidic pen for selectivly writing lines of different colors, includes a colorant mixing chamber and a writing tip in communication with the colorant mixing chamber; a plurality of colorant reservoirs disposed in the pen and which contain different colorants; microkinetic pump selectively effective to deliver colorant in selected amounts from the colorant reservoirs to the colorant mixing chamber wherein the colorants are mixed to provide a colorant of the desired color. The color is selected by a user and actuates the microkinetic pump to cause the desired amount of colorants to be delivered to the colorant mixing chamber where the writing tip can write a line of the desired line colors.
