12. The unit dose solid textile-treating article of claim 1 , wherein the coating completely surrounds the water-soluble core.

13. The unit dose of solid textile-treating article of claim 1 , wherein the water-soluble polymer is a polyalkylene glycol, a polyethylene glycol, a polyethylene terephthalate, a polyvinyl alcohol, or any mixture thereof.

14. The unit dose solid textile-treating article of claim 1 , wherein the colorant in the composition changes hue or becomes substantially colorless in the absence of the colorant stabilizer after a time period ranging from about 2 weeks to about 3 months.

15. A unit dose solid textile-treating article, comprising:

a water-soluble single-chamber container; and

at least one solid textile-treating composition, which comprises:

(a) a water-soluble core comprising a water-soluble carrier;

wherein the water-soluble core is in particle form having an average particle size from about 0.1 mm to about 50 mm;

(b) a coating that at least partially covers the water-soluble core, the coating comprising:

(i) a water-soluble polymer;

(ii) a colorant; and

(iii) a colorant stabilizer having a molecular weight of 1000 daltons or less;

(c) a flow aid mixed into the coating such that the flow aid is partially or fully exposed on an outer surface of the coating;

wherein the colorant stabilizer is an alkyl carboxylic acid, a cycloalkyl carboxylic acid, heterocycloalkyl carboxylic acid, an aryl carboxylic acid, heteroaryl carboxylic acid, a cycloalkyl alkyl carboxylic acid, an aryl alkyl carboxylic acid, a heterocycloalkyl alkyl carboxylic acid, a heteroaryl alkyl carboxylic acid, or any combination thereof;

wherein the at least one solid textile-treating composition does not contain a polysaccharide;
