The present invention provides a coloring composition which contains a coloring agent and a resin, wherein: the coloring agent contains a compound Y in which a compound represented by formula (1) is coordinated to a metal atom; and the content of the compound Y in the total solid content of the coloring composition is not less than 1% by mass but less than 10% by mass. In formula (1), R1 represents a hydrogen atom, an alkyl group or an aryl group; each of R2 to R11 independently represents a hydrogen atom or a substituent, and two moieties adjacent to each other among the R2 to R11 moieties may combine with each other to form a ring; and at least one moiety among the R2 to R11 moieties represents a substituent. The present invention also provides a film, an optical filter, a solid-state imaging element and an image display device, each of which uses this coloring composition.
