        The Windsor & Newton watercolour marker is a good clear strong yellow. It mixes well with other colours. I will be back to buy more colours in this range. It is excellent for doing swirls, curvy lines and fine lines. As well as a paint brush it is a watercolour pencil.  I can see lots of potential for this marker for any watercolour artist. Heather B
