The present invention relates to the field of color filters and LCDs. More specifically, the invention relates to a colorant composition for making color filters comprising pyrimido[5,4-g]pteridine derivatives of formula (I) wherein A1, A2, A3, and A4 are each independently of the others -NR1R2, wherein R1 and R2 are each independently of the others hydrogen, CrC8alkyl, -CO-C1-C8alkyl, -CO-Ce-Cuaryl, -COO-C1-C8alkyl, -COO-Ce-CMaryl, -CONH-d-Cbetaalkyl or -CONH-Ce-CMaryl, Or A1, A2, A3, and A4 are each independently of the others -OH, -SH, hydrogen, CrC8alkyl, CrC8alkoxy, or C6-C14aryl or -O- C6-C14aryl each unsubstituted or mono- or poly-substituted by halogen, nitro, cyano, -OR10, -SR10, -NR10R11, -CONR10R11, -COOR10, -SO2R10, -SO2NR10R11, -SO3R10, -NR11COR10 or by -NR11COOR10, wherein R10 and R11 are each independently of the others hydrogen, CrC8alkyl, C5-C12cycloalkyl or C2-C8-alkenyl; and to their use for color filter production and to color filters comprising said pyrimido[5,4- g]pteridine derivatives of formula (I).
