In modern use 'glas' is blue, 'gwyrdd' is green and 'llwyd' is grey, but colours yn Gymraeg are less about definitive shade names and more about interpretations of our environment. Our colours are a lot more culturally influenced than your average Dulux paint chart.
In this video we're going to look at the etymology of these hues & many other Cymraeg colours to try and explain the interpretive nature.
Seeing the world through Cymreig eyes might also make our mythology, folklore and poetry easier to understand
Mwynha! (Enjoy!)
