The element of colour clearly stands out in the work of Dutch artist José Heerkens, who is primarily concerned with the balance between line and colour. The interaction between the different amounts of paint applied in the form of bars is a theme that she explores with almost scientific meticulousness. In the process, different phenomena come into relation with each other: on the one hand, there is the quantity and density in which the colour material is used. From this, an extremely interesting interplay develops in the interstices, which have been deliberately kept open, both in the width and (due to the varying transparency of the paint application) in the depth of the pictorial space. A clear preponderance is given to the horizontal lines, which shift the spatial expression outwards, whereas the vertical lines form a kind of frame that lends firmness to those imaginings.
