No clear requirements for black and white color on onboarding

Bug Report

• Design team have not given us a clear explanation of how this is to be handled for black and white yet so we are unable to build it correctly. IMO it is probably better that we remove this option, will this discuss with design team but for now it will not be working correctly as long as it is selectable.
