Description
The author is discussing the differences between Blu and Mars Black watercolours. Blu is a more pure pigment mixture, with no blending powders or additives, while Mars Black is a more blended mixture with blending powders. The author also points out that Blu's lightness is due to the paper's whiteness, while Mars Black's darkness is due to the blending powders.
MaimeriBlu features an absolute purity of pigments that, together with gum arabic, compose the totality of the mixture. Imperceptible, transparent, clean. No blending powders, and no additives. Nothing harmonises or synchronises the shift between the various shades. The real value lies in the transparency of its colours and in the freshness of its washes. It is the whiteness of the paper that illuminates this type of painting. The light is behind the colour.
