This is the exact same outfit, just in two different lights.The yellow, indoor light really highlights the green qualities of the turquoise cardigan, and the cool, blueish natural evening light makes all the blue clothes look more similar in hue. The colours in bright white light are more like indigo (skirt), azure (button down), and turquoise (cardigan). They're all blues, but very different blues.
More on colour in the next segment about colour schemes.
