The type of colour theory used in this scenario is the subtractive colour theory. This theory states that when light is reflected off of an object, the colours that are not absorbed are the ones that are seen. In this case, when Emmaline looks at the sky, her brain is identifying the colour cyan because the blue and green wavelengths of light are being reflected off of the sky and not being absorbed.
