Sunlight is extremely important for most plants to grow and strive. Plants deprived of this light will lose color and die, however, plants CAN survive with indirect light, for certain plants they should be in indirect light versus direct sunlight. When plants aren't getting the sunlight they need, they will tend to grow upward rapidly, in search of light before it is too late.
I hypothesize that the plant will grow rapidly in search of light, and if it cannot get the sufficient amount of light it needs, the plant will lose its color and eventually die.
Hope this helps!
