White Opaque Details on Watercolour

July 14, 2023 | 6 Comments

I often get asked how I add white details over the top of watercolour. I’ve tried lots of different things but always come back to the Uni-ball Signo broad gel pen. It’s convenient and easy to find in all kinds of stores in Australia.

The trick to getting good results with this pen is to make sure that your watercolour paint is totally dry before drawing over it.

I have often said that the gel pen works best over dark pasty washes but this test proves that the pen works fine over watery washes of light value as well. You just have to make sure that the watercolour is dry!

Two other tips for using this pen (thanks to Liane for reminding me that I do these)… draw slowly and hold the pen vertically.

Some people use paint pens, gelly roll gel pens or gouache. What do you use?
