In accordance with the present invention there is provided a system and method for featuring information on a record. The system and method utilize reactant and coreactant compositions which are formulated to produce a color-changing reaction when brought together. The system and method also utilize a record having first and second areas disposed adjacent to each other. The second area is generally treated with the reactant composition. The coreactant composition is formulated to exhibit a first marking color on the first area of the record and to produce a color-changing reaction with the reactant composition on the second area of the record. The color-changing reaction effects a second marking color on the second area. The system and method further utilize a writing implement containing the coreactant composition. The implement is used to deposit the coreactant composition on the first and second areas in the form of symbolic information.
