Working from the original on a duplicated layer, the 'Colour Balance' option changed the colour range itself resulting in a more pale palette.

Due to the lack of striking appeal from the Colour Balance option, Hue and Saturation changed the colours as well its lightness and darkness. This gave more eye catching ranges to these images.
My preferred colour is the original (Pinks & Purples) edited via the Hue and Saturation tool.
