The power of lightning is determined by the attraction between the negatively and positively charged particles in the clouds, the stronger the attraction, the stronger the lightning is. Lightning is but an gigantic electrical discharge in air, and the color of an electrical discharge is determined by the gas surrounding it. Electrical discharge in air is whitish with a slight tinge of blue.
