(b) a silicone resin, wherein the silicone resin is a MQ resin;

(c) an ether of a water-soluble polyhydric alcohol;

(d) one or more pigments or one or more coloured materials;

(e) a thickening system comprising:

a deposition enhancer, wherein the deposition enhancer is a hydrophilic and non-ionic polymer, and wherein the deposition enhancer has a weight average molecular weight of from about 700,000 Dalton to about 3,000,000 Dalton; and

a thickening polymer, wherein the thickening polymer has a weight average molecular weight of at least about 10,000 Dalton, and wherein the thickening polymer is a cationic thickening polymer or is a non-ionic thickening polymer.

2. The composition of claim 1 , wherein the composition comprises one or more pigments having an average particle size of from about 5 μm to about 60 μm.

3. The composition of claim 1 , wherein the composition is in powder form.

4. The composition of claim 1 , wherein the composition comprises one or more coloured materials, wherein the one or more coloured materials is selected from the group consisting of: coloured fibres, coloured beads, coloured particles, coloured nano-particles, coloured polymers comprising covalently attached dyes, particles having diffraction properties, and combinations thereof.

5. The composition of claim 1 , wherein the one or more pigments are selected from the group consisting of metal oxides, hydroxides and oxide hydrates, mixed phase pigments, sulfur-containing silicates, metal sulfides, complex metal cyanides, metal sulfates, chromates and molybdates, and the metals themselves, and combinations thereof.

6. The composition of claim 1 , wherein the composition comprises from about 35% to about 60% of the one or more pigments, by total weight of the composition.

7. The composition of claim 1 , wherein the deposition enhancer conforms to the formula H(OCH2CH2)nOH wherein n has an average value of from about 20,000 to about 50,000.

8. The composition of claim 1 , wherein the aminosilicone polymer is a polydimethylsiloxane polymer having a sidechain with from 3 to 8 carbon atoms.

9. The composition of claim 1 , wherein the ether of a water-soluble polyhydric alcohol is selected from the group consisting of diethylene glycol monobutyl ether, ethylene glycol monohexyl ether, and a mixture of diethylene glycol monobutyl ether and ethylene glycol monohexyl ether.

10. The composition of claim 1 , wherein the composition is anhydrous.

11. The composition of claim 1 , wherein the aminosilicone polymer is a polydimethylsiloxane polymer having graft amino groups.

12. The composition of claim 1 , wherein the composition is substantially free of compounds causing precipitation of any component of the composition when the composition is in aqueous solution at pH of about 5 and at about 23° C.

13. The composition of claim 1 , wherein the deposition enhancer conforms to the formula H(OCH2CH2)nOH wherein n has an average value of from about 40,000 to about 50,000.

14. A method for providing a film comprising one or more pigments or one or more coloured materials onto keratin fibres, the method comprising applying the composition of claim 1 as an aqueous solution onto keratin fibres and allowing the keratin fibres to dry or drying them.

15. A kit comprising:

the composition of claim 1 , or a plurality of compositions of claim 1 , wherein each composition comprises a different pigment or coloured material;

an applicator.
