Who is usually given credit for the invention of the red-figure technique as seen in the amphora of Achilles and Ajax playing a dice game?

The red-figure technique is usually credited to the ancient Greek potter and painter Andokides, who is believed to have developed it around the late 6th century BCE. This innovation allowed for greater detail and complexity in depicting human figures, as the red-figure style involved painting the background black while leaving the figures in the natural red color of the clay. The amphora of Achilles and Ajax playing a dice game showcases this technique, illustrating its artistic potential.
