However, about 30% of the Pantone system's 1114 spot colors (as of year 2000) cannot be simulated with CMYK but with 13 base pigments (14 including black) mixed in specified amounts, called base colors. Those 1114 colors included 387 colors with numbers 100 to 487 from 1975 and some lighter colors from 600 to 732 in 1991. The original four-digit colors introduced in 1987 were remapped into three digits.
