Definition: Mae’r term hwn yn cael ei ddefnyddio weithiau i gyferbynnu â ‘Duder’ fel nodwedd yn disgrifio lliw croen, ond nid oes diwylliant penodol yn perthyn iddo.
Notes: Daw'r term hwn o gasgliad y Grŵp Gorchwyl a Gorffen ar Derminoleg ym maes Cydraddoldeb o ran Hil ac Ethnigrwydd. Diffiniad a nodiadau defnydd y Grŵp a gofnodir gyda'r cofnod hwn: "PEIDIWCH â defnyddio priflythyren ar ddechrau ‘gwynder’ gan nad oes dimensiwn diwylliannol iddo. Yr unig eithriad yw lle bo angen cysondeb rhwng dwy ddogfen yn y ddwy iaith a bod yn rhaid i’r cyfieithiad ddilyn arddull y gwreiddiol." Gweler hefyd y cofnod am Blackness/Duder.
