Carl Abraham Rothstén keeps values measured and balanced, a hallmark of tonal restraint. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #7C4F2C - appears at just 9.2%, deployed as a precision accent against the quieter ground. The value range of 52 units sits in the comfortable middle: enough depth, enough light, neither extreme. Palette 4 sits within the larger chromatic argument that Carl Abraham Rothstén's complete body of work advances.
