Dear candidate for passport size photo you must choose white background. As per the guidelines of NTA -

• Latest photograph
• White background
• 80% face coverage, ears clearly visible, on white background

Size - 10 Kb to 200 Kb

Format - JPG

So, choosing any other colour may lead to problems and mail by NTA to change the photograph.

All the best

Hope this helps
