Why isn't steam/cloud blue like liquid and solid water? Most of us here are aware as I think that pure water has a natural quest to absorb visible red colour wavelength slightly due do which liquid water and sometimes even ice appears to have a blue colour tinge. 
But even gaseous water(water vapour or steam) also absorbs red, rather it absorbs more strongly the red then liquid and solid water due to absence of hydrogen bonding. 
So why don't clouds/ masses of suspended water vapour appear blue. Why do clouds simply  scatter/reflect the white light that falls upon them instead of simultaneously absorbing the red from white llight along with scattering of white light and finally appearing blue just like water.

In this link look up in "What is the role of hydrogen bonding"  section.
 A: The white colour of clouds is due to Mie scattering. This arises because the refractive index of water is different from air. If the particles are large enough all wavelengths are scattered equally so there is no change in the colour of the scattered light. This is the case in clouds where droplet sizes are typically 10 to 20 microns.
The light scattering is from the surface of the drops i.e. the air/water interface. There will be some light transmitted through drops and hence some red absorption, but this is small compared to the Mie scattering so any colour shift is too small to see. Nevertheless the light colour does shift to the blue on cloudy days. Photographers judge the light colour by the colour temperature. Regular sunlight is around 5,700K and temperatures higher than this are bluer while lower temperatures are redder. On cloudy days the colour temperature is higher so the light is bluer. Google for related articles - a quick Google found this article that seems to me to give a good overview.
