Why are gliders almost always painted white?

to easily hide in clouds
to reduce solar heating
to make gliders distinguishable from other aircraft
to allow quick replacement of damaged parts
Since fiber­glass resin softens at high tem­per­a­tures, white is used almost uni­ver­sal­ly to reduce the tem­per­a­ture rise caused by solar heating. Less popular non-­fiber­glass gliders (those made of aluminum and wood) can be painted any color.
