Old Wood Natural Oil Colours Walnut - Dark Brown (Junglans regia) Walnut ?-Dark Brown is the neutral hue that OLD WOOD has developed to correct the red hue. OLD WOOD has developed an exclusive brown pigment, made with a unique process. The Walnut- Dark Brown colour has two applications. On the one hand it gives a walnut colour with a glaze effect of incomparable luminosity and warmth. On the other, it can be used as a tint or neutralising colour agent, which is where its exclusivity is appreciated. General speaking, to darken a colour we can always turn to its complement, or use black, being careful not to use too much, as it can look cold and usually diminish the desired transparency. The aim is to maintain a harmonic colour balance, in which all the different nuances are apparent, without distortion or excessive darkening. Walnut - Dark Brown is the neutral shade that OLD WOOD has developed to correct the red or any other colour that has been used to excess, while maintaining transparency, enhancing the hue and correcting the excess without dirtying it and, what is most important, enriching the nuances. 8 ml.
