1. An aqueous color composition for paper and/or paperboard having a solids content of 60-74 wt. % and consisting of: a pigment selected from the group consisting of calcium carbonate, kaolin, calcinated kaolin, talc, titanium dioxide, gypsum, chalk, satine white, barium sulphate, sodium aluminium s
1. An aqueous color composition for paper and/or paperboard having a solids content of 60-74 wt. % and consisting of: a pigment selected from the group consisting of calcium carbonate, kaolin, calcinated kaolin, talc, titanium dioxide, gypsum, chalk, satine white, barium sulphate, sodium aluminium silicate, aluminium hydroxide and any mixture thereof,optionally starch and/or known additives used in coating compositions selected from the group consisting of preservatives, dispersing agents, defoaming agents, lubricants, hardeners, optical brighteners, and a combination thereof,- optionally a latex binder selected from the group consisting of styrene butadiene (SB), styrene acrylate (SA), polyvinyl acetate (PVAc) latex, and any combination thereof,a binder substitute, wherein the binder substitute is a styrene acrylate copolymer comprising a starch having a mean particle size less than 80 nm and obtained by copolymerization of ethylenically unsaturated monomer in the presence of a starch having an amylopectin content >80 wt. % and an intrinsic viscosity from 0.05 to 0.12 dl/g, andwater. 2. The coating color composition according to claim 1, wherein the mean particle size of the binder substitute is 40-70 nm. 3. The coating color composition according to claim 1, wherein the latex binder is styrene butadiene latex. 4. The coating color composition according to claim 1, wherein an amount of the pigment, latex binder, binder substitute and known additives is as follows: 100 parts of total pigment,greater than 0 to 12 parts of the latex binder,1.5- 9 parts of the binder substitute, and0- 3 parts of known additives, provided that a total amount of the latex binder and the binder substitute is at least 5 parts. 5. The coating color composition according to claim 1, wherein an amount of the pigment, starch, latex binder, styrene binder substitute and known additives is as follows : 100 parts of total pigment,4- 12 parts of starch,3- 6 parts of the latex binder,2- 4 parts of the styrene binder substitute, and0- 3 parts of known additives. 6. The coating color composition according to claim 1, wherein an amount of the pigment, latex binder, binder substitute and known additives is as follows : 100 parts of total pigment,4- 5 parts of the latex binder,2- 3 parts of the binder substitute, and0- 3 parts of known additives. 7. The coating color composition according to claim 1, wherein the coating color composition has a solids content of 63-72 wt. %. 8. Paper or paperboard coated with a coating color composition according to claim 1.
