Georgia O'Keeffe works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 64.9% of the palette belongs to #FCF6EA, a concentration that makes it the unmistakable visual centre. Only 5.6% is devoted to #2F679F, yet that small allocation delivers the palette's entire chromatic tension. 57 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Georgia O'Keeffe's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
