What is claimed is: 1. A fluid supply assembly comprising a reusable plastic cup holder, a lid having an opening therein, and a flexible, disposable cup positioned in the reusable cup holder, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the disposable cup being see through, the disposable cup collapsing as the fluid is dispensed, the lid covering the open outlet end of the disposable cup, the disposable cup comprising a polymeric material containing an antistatic additive, the antistatic additive preventing chargeable particles in a coating mixture from sticking to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed. 2. The fluid supply assembly of claim 1 wherein the antistatic additive is selected from long-chain aliphatic amines and amides, phosphates, quaternary ammonium compounds, polyethylene glycols, glycol esters, ethoxylated long-chain aliphatic amines, polymeric antistatic additives composed of hydrophilic copolymers, intrinsic conductive polymers, polyaniline, polythiophene, conductive fillers, carbon black, metal powder, metal fibers, or graphite fibers. 3. The fluid supply assembly of claim 1 wherein the polymeric material is selected from polyethylene, or polypropylene. 4. The fluid supply assembly of claim 1 wherein the polymeric material comprises a see through polymeric material. 5. The fluid supply assembly of claim 1 wherein a flange extends outward from an edge of the outlet end of the disposable cup. 6. The fluid supply assembly of claim 5 wherein the outlet end defines an axis, and the flange extends downward from the axis of the outlet end at an angle in a range of from about 10° to about 70°. 7. The fluid supply assembly of claim 5 wherein the flange of the disposable cup further comprises a removal tab. 8. The fluid supply assembly of claim 1 wherein the disposable cup has indicia for measuring fluids on the side wall. 9. The fluid supply assembly of claim 1 wherein the side wall is generally cylindrical. 10. The fluid supply assembly of claim 1 wherein the side wall is generally elliptical. 11. The fluid supply assembly of claim 1 wherein the side wall has a generally cylindrical lower side wall portion and generally frustoconical upper side wall portion. 12. The fluid supply assembly of claim 1 wherein the side wall has a generally cylindrical lower side wall portion, a generally frustoconical intermediate side wall portion, and a generally cylindrical upper side wall portion. 13. The fluid supply assembly of claim 1 wherein the side wall is generally cylindrical and an upper end of the side wall is connected to a flange by a flat annular portion. 14. The fluid supply assembly of claim 1 wherein the side wall has a generally elliptical lower side wall portion, a generally cylindrical upper side wall portion, and an intermediate side wall portion extending from the lower side wall portion to the upper side wall portion. 15. The fluid supply assembly of claim 1 wherein the side wall has a generally cylindrical lower side wall portion, a generally cylindrical upper side wall portion, and an intermediate side wall portion extending from the lower side wall portion to the upper side wall portion. 16. The fluid supply assembly of claim 1 wherein the side wall extends between the outlet and the bottom, the side wall has a first portion adjacent to the outlet end, the side wall having a second portion adjacent to the bottom, the side wall having a third portion between the first and second portions, the first and second portions having a thickness greater than a thickness of the third portion. 17. The fluid supply assembly of claim 16 wherein the thickness of the first and second portions is in a range of about 2 to about 3 times the thickness of the third portion. 18. The fluid supply assembly of claim 16 wherein the thickness of the first and second portions is in a range of about 0.006 in. to about 0.015 in. 19. The fluid supply assembly of claim 16 wherein the thickness of the third portion is in a range of about 0.003 in. to about 0.005 in. 20. The fluid supply assembly of claim 16 wherein the first and second portions each cover about one fourth of the side wall. 21. The fluid supply assembly of claim 16 wherein a thickness of the bottom is in a range of about 0.003 in. to about 0.02 in. 22. The fluid supply assembly of claim 1 wherein the fluid supply assembly is a paint supply assembly, and wherein the coating mixture is a paint mixture and the chargeable particles are metallic particles, and wherein uniformity of the coating mixture is uniformity of a color of the paint mixture. 23. The fluid supply assembly of claim 1 wherein the reusable cup holder mates with the lid, and the disposable cup is sealed within the reusable cup holder and the lid. 24. A method of maintaining uniformity of a coating mixture during dispensing comprising: providing a reusable plastic cup holder and a lid having an opening therein; providing a disposable cup adapted to fit in the reusable cup holder, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the disposable cup comprising a polymeric material containing an antistatic additive, the antistatic additive preventing chargeable particles in a coating mixture from sticking to the disposable cup, the disposable cup being see through; filling the disposable cup with a coating mixture containing chargeable particles; placing the disposable cup in the reusable cup holder; covering the open outlet end of the disposable cup with the lid; connecting the opening in the lid to a spray gun; and dispensing the coating mixture, the disposable cup collapsing as the coating mixture is dispensed, whereby the chargeable particles in the coating mixture do not stick to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed. 25. The method of claim 24 wherein the coating mixture is a paint mixture and the chargeable particles are metallic particles, and wherein uniformity of the coating mixture is uniformity of a color of the paint mixture. 26. A fluid supply assembly comprising a reusable plastic cup holder and a lid having an opening therein, the reusable cup holder mating with the lid, and a flexible, disposable cup positioned in the reusable cup holder, whereby the disposable cup is sealed within the reusable cup holder and the lid, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, a flange extending outward from an edge of the outlet end of the disposable cup, wherein the outlet end defines an axis, and the flange extends downward from the axis of the outlet end at an angle in a range of from about 10° to about 70°, the disposable cup being see through, the disposable cup collapsing as the fluid is dispensed, the disposable cup comprising an antistatic material so that chargeable particles in a coating mixture do not stick to the disposable cup so that uniformity of the coating mixture is maintained while it is dispensed. 27. A paint supply assembly comprising a reusable plastic cup holder, a lid having an opening therein, and a flexible, disposable cup positioned in the reusable cup holder, the disposable cup comprising a side wall, an open outlet end, and a closed bottom defining an interior, the disposable cup collapsing as the paint is dispensed, the lid covering the open outlet end of the disposable cup, the disposable cup comprising a polymeric material containing an antistatic-and-see-through amount of an antistatic additive to prevent metallic particles in paint from sticking to the disposable cup so that uniformity of the color of the paint is maintained while it is dispensed and to provide the see through disposable cup.
