4X4 Toned Winter by Ferial. In 4x4 colours of " pure" seasons does not mean palettes with pure hues. "Tinted" seasons are not simply tints. " Toned seasons" are not just the palette with colors toned. " Shaded" seasons have not only shades of the palette colors. Every season in 4 x 4 has a "tinted, toned, shaded, and pure" version. That means the lightest, the most muted, the darkest, and the purest version of colors for that season.
