To provide a color composition from which a film with light absorption anisotropy having an excellent dichroic ratio can be formed, a dichroic dye compound, a film with light absorption anisotropy, a laminate and an image display device.SOLUTION: A color composition of the present invention comprises: a dichroic dye compound having a Hansen solubility parameter of 17.5 or greater and having a structure represented by a formula (1) below; and a liquid-crystalline compound. In the formula (1), A, Aand Aeach independently represent a divalent aromatic group which may have a substituent, provided that any one of A, Aand Arepresents a divalent thienothiazole group which may have a substituent. In the formula (1), Land Leach independently represent a substituent.SELECTED DRAWING: None
