* Not a "true" variant, Rainbow Chess differs from standard Chess only in the specifications (colors) of the physical material employed. It is in fact a restricted implementation of standard Chess and follows all the regular rules of play with no change at all

Rainbow Chess is a proposed extension of the standard chess game that attempts to keep full compliance to the official rules while at the same time adding an element of color that arguably makes the game more interesting and perhaps easier to learn.

In Rainbow Chess there is still a player using "white" (more accurately, lighty-colored) pieces while his opponent uses "black" (actually dark) pieces. But the pieces have their own colors, in different shades to allow for the two players; a suggested pattern is to have pawns in black and white, kings in red, queens in purple, bishops in blue, knights in yellow and rooks in green.

Its inventor was Pál Suvada, and it has been endorsed by GM András Adorján. Rainbow Chess was played in 22 July, 1994 at Budapest as a part of Béla Papp Memorial, reportedly with good acceptance.
