How do I get my iPad's screen back to displaying in color?

[iMore Question]

Screen turned from color to black & white how do I get color back on my screen?

Settings - General - Accessibility and disable 'Grayscale'. If you didn't enable grayscale, make a genius bar appointment with the nearest Apple Store to have them fix the problem for you.
