If you mean it faded to a lighter shade, that would be considered normal. If you mean it totally changed to another color, then the color admixture would be the problem - possibly because the color admixture was not fully mixed in with the mix so it released concentrated color in spots (causing a spotty ro streaky appearance, not a uniform color change), or the color additive was not color-fast so it leached or bleached out.

Who is at fault - probably the concrete company unless the contractor was mixing on-site and added the admixture himself during mixing. The responsbile party, if a color change rather than than just tonal change, would be who you paid for the concrete - the contractor who placed it unless you paid for the concrete directly.

If you mean a stained concrete, rather than mixed-into the mix color, then the contractor who you paid for the staining job. In this case I have seen a few things in contractor blogs about organic (vegetable based) liquid dyes being sold for grout andc oncrete coloring - a BAD idea as organic dyes are generally not at all colorfast in sunlight, and many may not be colorfast in the chemical environment of concrete either.
