A gel composition comprising:
- (a) a component selected from the group consisting of aqueous dispersion(s) comprising a binder(s), aqueous emulsion(s) comprising a binder(s), and combinations thereof, wherein the component has a minimum film forming temperature of 22.degree. C. or less;
- (b) a thickening agent of a type and in a sufficient amount to provide the composition with Bingham plastic properties when shear is applied to the composition;
- (c) optionally additional water beyond that which is present due to the aqueous nature of the component of element (a);
- (d) a water dispersible inorganic pigment(s);
- and
- (e) optionally a pH adjusting agent;
- wherein the pH of the composition falls within the range of about 6 to about 9.
