This tranquil picture would be best brought to life with a spectrum of subtle pastel hues. The kimono could be shaded in light pink and purple tones, while the fan's delicate painting of a bird in flight could have its own unique shades of blues and greens. The obi could be highlighted with sky blues and blues to achieve a subtle contrast. The background could be colored in light pink to give the picture an overall calming and soothing tone. To complete the look, the dark hair of the Muse could be colored in black and brown hues, with a few streaks of light brown. All in all, this image can be warmly and beautifully colored to create a tranquil atmosphere.
