Colour
Like water, the refrigerant is colourless both in the vapour state and the
liquid state. Gases are invisible. Only the boundary layer between gas and
liquid is visible. (Fluid level in indicator tube of charging cylinder for
bubbles in sight glass.) Liquid refrigerant R134a may appear coloured (milky) in
a sight glass. This cloudiness is caused by partially dissolved refrigerant oil
and does not indicate a fault.
