Abstract
An illuminated marking device is described for use with colorless marking materials. The marking materials remain colorless until being transferred to a marking surface having a developer material disposed thereon that causes the marking material to develop a colored appearance. The marking material is contained within a marking device having a clear or translucent barrel and a lens integrated into a first end. The lens is tinted in a color similar to that of the developed color of the marking material. The first end of the marker is inserted into a light housing having a light source therein. Light from the light source is filtered by the lens and thereby illuminates the barrel of the marker in a color similar to that of the developed color of the marker. The glowing marker indicates the marking color of the marker and provides an enjoyable glowing experience.
