The launch of the oil paint series in the unique range of 168 colours was followed by the Old Holland Classic Watercolours in the same rich range. One of the unique characteristics of these watercolours is the unparalleled colour strength (maximum pigmentation). And while this high colour strength requires a slightly different approach on the part of the aquarellist (so little paint is needed from the tube or cup for the desired colour effect that you have to get used to the ratio of paint to diluent), the advantages are clear.
