The colour changes the character of the ripple quite dramatically. Olive and Viridian Green have a natural, slightly earthy quality, while Blue introduces a cooler depth. Soft Pink brings warmth without feeling too strong, and Pearl and White create a much lighter backdrop where the surface texture becomes the main source of interest.
With the stronger colours, I'd resist the temptation to match every surrounding finish. The ripple is already adding another layer of visual detail, so natural timber, simple stone and quieter painted surfaces can give the tile enough space.
The lighter shades offer more freedom to introduce contrast elsewhere. A dark vanity or metalwork, for example, can make White or Pearl Riviera feel much more contemporary than the tile's traditional influence might initially suggest.
