wales flag dragon symbol The colors on the Welsh flag represent the following:
White - peace and honesty
Red - hardiness, bravery, strength & valour
Green - hope, joy and love and in many cultures have a sacred significance
The red dragon became the symbol of the Welsh nation through its adoption by the Tudor ancestors of king Henry VII.
Edmund and Jasper Tudor had a dragon as crest granted them by Henry VI.
When Henry Tudor faced king Richard III at the battle of Bosworth in 1485 he had three recognized battle standards. One of these showed "Red ffyry dragon peyntid upon white and Grene Sarcenet". (red "fire" dragon with raised forearm on a white & green background)
It is held that this dragon banner represented Henry Tudor's claim as a true representative of the ancient kings of Britain and was a tribute to the Welsh people who had made his victory possible.
