1. A dispersion containing a dispersed phase comprising droplets and a continuous aqueous phase, wherein the droplets comprise at least one fatty phase,
wherein the fatty phase comprises at least one pigment in a content higher than 23.5 weight % relative to the weight of the fatty phase, and wherein the fatty phase also comprises at least one lipophilic gelling agent,
wherein said lipophilic gelling agent is selected from the group consisting of: organic or mineral, polymeric or molecular lipophilic gelling agents, and mixtures thereof; and wherein the lipophilic gelling agent is not a polyorganosiloxane;
wherein said mineral lipophilic gelling agent is selected from the group consisting of: hectorites modified by C10 to C22 ammonium chloride, hectorite modified by distearyl dimethyl ammonium chloride, hectorite modified by distearyl dimethyl ammonium chloride, benzalkonium and quaternium-18 bentonites, and clays modified by stearyldimethylbenzoylammonium chloride, and
wherein the droplets have a diameter larger than 500 μm and represent a volume equal to or greater than 60% of the total volume of the dispersed phase, and/or at least 60% of the droplets have a mean diameter larger than 500 μm,
wherein the droplets also comprise a shell, said shell comprising at least one anionic polymer and at least one cationic polymer, and
wherein the dispersion does not comprises a surfactant.
