FIELD: material for painting, which prevents appearance of accidental colored marks on the surfaces that are not intended for it. SUBSTANCE: the system contains a composition including at least one predecessor of the color, containing leuco dye in an optically transparent low- volatile solvent, having a viscosity of 12sP or less, in a concentration sufficient for stabilization of the leuco dye and good color generation after development, substrate having a coating containing a color development initiator, and a painting tool for application of the above composition, with formation at least of one color mark manifesting an instability on fabric, expressed in indices ΔE, where ΔE equals approximately 5 or less. The system for painting inhibits an undesirable painting, but if painting has already occurred, the given in foreseen spots may be washed off. EFFECT: facilitated procedure. 57 cl, 8 tbl, 12 ex
