The public was amazed by the rainbow. Many netizens are perpetuating moments like this to be disseminated to social media.

"Normally, the appearance of a rainbow is caused by water droplets in the atmosphere that reflect sunlight into different color spectra," says Simon King.

"In addition, the rainbow appeared at sunset at that time the sky was shades of pink, plus the position of the lower sun so that the color purple, blue and green in the rainbow increasingly reduced," he said.
