The entire range of Isaro watercolours has been developed to give maximum transparency to the colours. Addtionally, the ingredients in the composition of the binder are all carefully selected.
Gum arabic varies in colour from very pale yellow to dark brown – the gum darkens on contact with the tannin in acacia bark. It is essential for Isaro to select a top quality acacia gum which, when dissolved in water, gives a clear solution to protect the luminosity of the pigments.
Glycerine and honey are added in very precise proportions to ensure the paste remains supple. A single-flower acacia honey was chosen, as good quality honey of this type is very clear.
The artist comes first and Isaro will grow and evolve with that principle in mind. I think that offering artists a quality product is the best way to be recognized. And so, I want to remain in close touch with the production of my colours because it’s the very essence of my profession. I am available for artists to answer questions by email.

Watercolour Paint.
This Is Isaro.
Welcome from Isabelle
My great-great-grandfather, Willem Roelofs, was a painter. You can see his painting in the Netherlands (Rijksmuseum and Gemmentemuseum), Belgium (Royal Museum of Fine Arts of Belgium), France (Royal Museum of Fine Arts of Lille) and his works are also exhibited in Brazil.
His son, my great grandfather, Albert Roelofs, was also a painter. He taught painting to Crown Princess Juliana from the Netherlands. At the beginning of the 20th Century he founded a small factory with his friends, including a chemist, where they made oil colours.
Albert’s knowledge as a discerning artist stood him in good stead for making quality oil colours which soon gained an enviable reputation amongst the members of artistic community. Albert died in 1920 at the age of 43, but the company continued until 1980 under the founding members and Albert’s son, my grandfather. My father helped my grandfather for a few years, moving the paint factory to Belgium where my father now lived.
It’s been 10 years since I created colours for artists. I think I have acquired, over the years, a rich expertise of experiences. I’ve worked with classical pigments (cadmium, cobalt, iron oxide …), modern pigments (quinacridones, dioxazine, DPP …) and historical pigments (cochineal, true indigo, smalt, azurite).
Welcome from Richard
I am excited for many reasons to have worked with Isabelle to bring you this collaboration, but particularly, as I am able to bring you the world’s first “Double Phthalo Green” – a combination of the two phthalocyanine greens (PG36 and the slightly more blue PG7). It’s a lovely transparent, highly lightfast paint and wonderful colour match to magenta. Cool name too! At this time, it’s available exclusively in our first curation.
You’ll also find below (and in each individual paint description) a full reference listing of the pigments used in each paint. You can shop using the menu links at the top of the page.
We are currently only shipping within Australia. You can contact me for any administrative or order enquiries. Send all technical or paint enquires to Isabelle at the above address. We do not currently have an offering for retail outlets and this is our privacy policy.
I am delighted to bring you Isabelle’s paints. Welcome to Isaro.
