Crayola construction paper crayons were first made in the 1990's. How do these crayons work? They let kids color on dark paper and the color shows up! An opacifier or a reflecting filler is added to the crayon. This opacifier helps the color show up on dark surfaces. The patent is also the same patents listed on the construction paper crayons.
My kids love coloring on dark color papers, and love all the products that Crayola has to do this, from the Gel Markers, to these Crayola Construction Paper Crayons. The marks from the crayons are also a lot more vivid on white paper also. They are the same thing as the Poster Crayons, but smaller.

It is interesting to note that the construction paper crayons went from a 52-5816 to 52-5817 style number change. The Canadian box uses a -235 code number. My guess would be that the formulation changed and this is how Crayola keeps track of the formulation change. The wrappers were also changed from a wooden color to black.
