Results of test
After 18 months in the sun, the NeoColors II crayons had not faded much at all. These are good for professional use. The Marabou Art Crayons had faded a lot. Both types of crayons are water soluble wax crayons.
The lightfastness marking of the NeoColor II was reliable except for the color “Orangish Yellow, 031” that is marked with three stars (***), the highest rating for lightfastness. It had faded a little bit.
