The value is different for each ink.
A felt pen is pretty much just your average, ordinary, everyday pen, such a as Bic, Papermate, etc.
Felt tip pens have a porous tip that allows ink to flow onto the writing surface. The ink is held in a reservoir inside the pen, and capillary action draws the ink to the tip when writing. The tip's fibers help regulate the ink flow and provide a consistent line thickness.
Pen colour is the colour of the ink ejected from the pen when it is used for its intended purpose (writing, or drawing). It is not necessarily the colour of the pen itself, either the casing (the outside) or the appearance of the ink cartridge inside.
A felt tip pen typically consists of a plastic barrel filled with ink, a felt material that acts as the tip, and a cap to prevent the ink from drying out. The tip is made of fibers that absorb and release ink as it glides across a surface, providing a smooth writing or drawing experience.
A Felt Tip pen has a tip that draws the ink from the pen and thru the tip onto the paper. A ball point pen has a metal time that houses a ball. When you press down on the tip and move it, the ball rolls and draws the ink from the pen and rolls it over to the paper.
