Uniquely identifiable inking instruments

A method of an inking instrument interacting with a computing device to generate digital ink, the method comprising:

• receiving a particular light at an inking instrument from a light emitting device;
• receiving input at the inking instrument selecting a light configuration to be generated by the inking instrument and at a time in which the inking instrument is in a color-sense mode, wherein the inking instrument comprises:
• a handle;
• a first light source and a second light source connected to the handle, wherein light that is generated by the first light source is visible light and light that is generated by the second light source is non-visible light;
• and
• bristles attached to the handle, comprising fiber optic bristles operably connected to at least the first light source and the second light source, and passive reflective bristles comprising a material that reflects the particular light with one or more first characteristics, wherein some of the fiber optic bristles are connected to the first light source to emit the visible light generated by the first light source and some other of the fiber optic bristles are connected to the second light source to emit the non-visible light generated by the second light source;
• with one or more second characteristics, and wherein the first and second characteristics enable the computing device to identify the light configuration of the inking instrument;
• based on the received input, selecting the light configuration and illuminating the first light source and the second light source according to the selected light configuration, thereby generating visible light from the first light source and non-visible light from the second light source, to emit the visible light and the non-visible light from the fiber optic bristles;
• simultaneously reflecting the particular light from the reflective bristles and emitting the generated visible and non-visible light from the fiber optic bristles proximate a display of a computing system, wherein the visible light indicates the light configuration to a user, and wherein the reflected particular light and the non-visible light have the first and second characteristics, respectively, and are received by one or more light sensing devices of the computing system, and which causes the computing system to:
• detect a location of the inking instrument relative to the display;
• identify the light configuration of the inking instrument based on the first and second characteristics;
• and
• display digital ink at the display with a first distinguishing feature corresponding directly to the selected light configuration, and corresponding to the location of the inking instrument.
