PROBLEM TO BE SOLVED: To obtain a discolorable drawing for coloring which is repetitively usable, is free of contamination by writing implements used for coloration and has excellent ease of convenience by making a non-discolorable image visible by the clarification or opacification of a porous layer in a water absorption state. SOLUTION: The surface of a base 2 is provided with the non-discolorable image 2 and part on the non-discolorable image 2 is provided with the porous layer 5. The porous layer 5 turns transparent or opaque by absorbing the water and makes the lower layer thereof visible. When the porous layer 5 of the portion where the water is absorbed dries, the porous layer 5 restores the original state and, therefore, this drawing for coloring allows the practicability of repetitive use. The porous layer 5 disposed on the non-discolorable image 2 is a layer formed by fixing low-refractive index pigments together with a binder resin in a dispersed state. The low-refractive index pigments include particulate silicic acid, barytes, low settling barium sulfate, barium carbonate, etc. The material of the base 3 is not particularly restricted and include synthetic paper, films, plastics, rubber, etc.
