So, what are they? Gansai Tambi (Gansai meaning "vibrance" and Tambi meaning "aesthetic") are artist quality Japanese paints that are described as watercolours, but have a very different feel and effect. Yes, they can be used as watercolours when watered down A LOT, but mainly they act similar to Gouache paints, which are much thicker and more opaque. Gansai Tambi are semi-transparent which is why they have been labelled as 'solid watercolours', but they handle more like a rich paint than watery ink. Also, instead of having a matte finish like watercolours they leave a slight sheen on the surface, making them look shiny and laquer-like.
But how do these perform on a colouring page? Well, unless you use them to make a very thin, watery wash, they shouldn't buckle the paper of most half-decent colouring books- purely because they're so thick. If using a narrow enough paint brush, Gansai Tambi perform amazingly well on small areas and leave you with a really stunning, vivid finish.
Here's a page I painted using Gansai Tambi only.
I hope you've enjoyed me showing you something a little different today, let me know what you think about using paints for colouring!
