The role of 1.25 inch ND Filter kit:

Effect on image color: It will only play a role in controlling the amount of light, and will not affect the color reproduction and reflection effects of the scene.

Impact on clarity: Clarity is not affected by the amount of light, and it does not become worse as the amount of light reduction increases.

Rich functions: ND can reduce the amount of light entering the lens, so use it to shoot some super bright light sources, or use the large aperture of the lens in bright light
