The aim is to speed up the game by reducing the number of on-field replays
Orange cards are being considered for this autumn's rugby World Cup.
Players can still be sent off for foul play but the referee will have the option of showing a yellow card that can then be upgraded to red on review by the Television Match Official.
A form of the yellow card review system is being trialled in Super Rugby Pacific and it could be fast-tracked into the global showpiece hosted by France this autumn.
The aim is to speed up the game by reducing the number of on-field replays while also dealing with contentious decisions.
