Graduated ND filters kinds:
Adapt high quality optical glass which is fine polished, and nano coated with AR film, so light light transmittance is very high, then definition is very good. To make low / no color difference, it's evenly coated by ND film which allows different wavelength of light to pass through it equivalently.
