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.
