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.
