What are Dulux Smokey Slate undertones?
Smokey Slate has a clear blue undertone based on its position in the color space. We identify undertones by isolating the pure hue (separating it from lightness and saturation), which avoids distortions caused by tints, tones, and shades.
This method is generally more reliable than judging undertones on a white background.
