Awhile back, I bought a set of Arteza watercolor brush pens: https://arteza.com/collections/real-brush-pens (not sponsored, really!)
I've started using brush pens at my day job and immediately fell in love with them! Convenient and mess-free version of watercolor art. These are a series of watercolor painting using a tutorial by Makoccinos...but I added a bit of things myself in the illustrations: https://www.youtube.com/watch?v=9P0ot0ifwXk&t=7s
Using the tutorial helped me re-learn watercolor painting and colors again.
