The bright colours in a slim size 100X400 well help to design the area as elegance and luxurious. It fully matches with the brick pattern for your kitchen clean splashback. As the colours for this size come only with alabaster and white, if you would like to apply mixed tile pattern, you can apply the alabaster as a point colour tile along to the white brick pattern as well.
The colour discrepancy may incur depending on the monitor specifications or resolutions.
