37ml tubes are available in 28 colours.
Each colour within this wide and balanced spectrum of colours, has been selected and formulated to offer the greatest choice so that artists can use a unique palette that best suits their work.
Since 1832 when Henry Newton and William Winsor introduced the first moist water colours to the world, much of our reputation for supreme quality has stemmed from the Artists' Water Colour range.
Since then Artists' Water Colour continues to be formulated and manufactured according to our founding principles; to create an unparalleled water colour range which offers artists the widest and most balanced choice of pigments with the greatest possible permanence.
The 37 ml tubes represent good value and are long overdue but I found the quinacridone gold is very watery. Martin Oates (GLASGOW) on 28 Oct 2008
I was a little worried that these tubes might have separated out as some I have bought in Australia have done, but all are in excellent condition, which is a great relief. I shall continue to buy most of my art supplies from KB on the other side of the world because the service is excellent, delivery fast and reliable, and the products in excellent condition.

This is my favorite WC brand and the 37ml tubes are both economical in the long run and convenient at home. Hope that W&N will increase the options in this size ... Eduardo Pire (Terrassa, Spain) on 19 Apr 2012
