A shadow stick is a vertical pole placed in the ground. Sunlight casts its shadow on to a level surface below (e.g. a sheet of card or just level ground The length and position of the shadow then depends on both the time of year and the time of day. Local noon can be found from the time when the shadow is shortest. At this time the Sun is highest in the sky and crossing the meridian. However, shadow sticks are not good clocks - the azimuth of the Sun's shadow at a given time changes throughout the year with the Sun's declination. http://www.nmm.ac.uk/server/show/nav.3117
A shadow stick is a simple tool used to estimate the time of day based on the length and direction of a shadow cast by the sun. By planting a stick vertically in the ground and monitoring the movement of its shadow throughout the day, one can make a rough estimate of the time.

How is the shape and size of shadow affected if coloured is used instead of white light?
The shape of a colored shadow remains the same as a white shadow because it is determined by the object casting the shadow. However, the color of the shadow is influenced by the color of the light source. For example, a red light will cast a red shadow, giving the illusion of a different color shadow. Size of the shadow is not directly affected.

Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves

You can use a sundial, which is a device that uses the position of the sun's shadow to tell time. By placing a stick or pointer on the sundial, the shadow it casts can indicate the time based on markings on the sundial's face.
