The present invention relates to organic peroxide formulations that contain a reactive, compatible dye or pigment and their use in systems involving free radical reactions such as monomer polymerizations, resin and elastomer curing and polymer modifications. The dye or pigment appears red in the organic peroxide composition and during mixing of the organic peroxide with monomers, polymers and other systems to which organic peroxides are typically added before their use to generate free radicals. Once conditions are applied to decompose the peroxide into free radicals, the desired curing, crosslinking or polymerization reaction occurs and the red color disappears. The red color does not persist in the product at the end of the reaction and therefore does not adversely affect the desired final color of the reaction product.
