Abstract: The present invention aims to provide an interlayer film for a colored laminated glass which exhibits a visible light transmittance Tv of 5% or lower, small variation in visible light transmittance and an excellent appearance when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), and a colored laminated glass produced using the interlayer film for a colored laminated glass. Provided is an interlayer film for a colored laminated glass exhibiting a visible light transmittance Tv of 5% or lower when incorporated in a laminated glass together with two clear glass plates in conformity with JIS R3202 (1996), the interlayer film for a colored laminated glass including a laminate of at least two layers including a first resin layer containing a thermoplastic resin and a colorant and a second resin layer containing a thermoplastic resin and no colorant, the first resin layer satisfying a ratio of a difference Δt1 in thickness between the maximum value t1max and the minimum value t1min to an average thickness (Δt1/average thickness of first resin layer) of 0.30 or less.
