Is better “color” or “black and white” for your profile photo in WhatsApp?
The best option is to use Color. Color is real. You need to provide trust, confidence and credibility. For all that color and a real photo will do the job. If you use “Black and White” or any other effect the only issue you will have is lack of confidence. Be upfront and provide a real photo of yourself.
Try to look smart and add a photo that is professionally shoot. If you can not do it, just put yourself in front of the light and try to have a neutral background.
Find a white or grey background and shoot your photo. If you are an artist, or a rapper then, maybe, you can do a more artistic photo, but for the 99,99% just use a standard photo.
