PROBLEM TO BE SOLVED: To obtain a fine green-based color pigment which does not contain a harmful element, has improved chemical resistance such as acid resistance, alkali resistance, etc., and improved heat resistance, and to provide a coating and a resin composition having excellent transparency by using the fine green- based color pigment. SOLUTION: This fine green-based color pigment comprises fine particle powder of green color complex hydrated iron oxide having >=0.005μm and <0.1μaverage size in major axis in which the surface of the particle is coated with an organosilane compound or a polysiloxane formed from an alkoxy silane and an organic blue pigment is attached to the coating. The amount of the organic blue pigment attached is 5-30 pts.wt. based on 100 pts.wt. of the hydrorated iron oxide fine particle power.
