Which pool tiles create which water colour? Glass mosaic for turquoise, blue, green and dark pools
Tiamont material guide · Pool & Spa
Pool water colour starts with the tiles
White can encourage crystal-clear pale blue, sand a warm turquoise, blue greater depth and dark shades a reflective water surface. The interplay of the lining, light, depth, surroundings and grout is decisive.
Why the lining changes the water's colour
Small amounts of pool water are almost colourless. In the pool, however, water absorbs warm components of light more strongly, leaving blue and green more visible. The pool tiles provide the reflective base colour: white, cream and light beige look bright, while sand and beige often produce turquoise to green-blue. Pale blue and turquoise enhance aqua; blue and teal create a richer blue. Green brings a lagoon character. Grey looks silvery to grey-blue, while anthracite and black create dark, reflective water.
Water palette 01
Crystal-clear pale blue
White and very light pool tiles reflect plenty of light. In sunny pools, they often create clear sky blue to pale turquoise. The effect feels spacious, fresh and particularly light.
SICIS® · Waterglass
Cloudwhite 20
Solid white glass tiles with a smooth, polished surface keep the base light and let reflections come alive.
Grout effect: Very light or matching grout creates a calm, bright surface.

Icewater 21
The white palette combines a bright base effect with the shimmering play of light in polished glass.
Grout effect: Light, neutral grout supports clarity without strong outlines.

Caribbean turquoise
Light sandy, beige and aqua shades can encourage warm turquoise to green-blue. Plenty of sunshine and light stone surfaces around the pool enhance the airy resort feel.
SICIS® · Natural
Sand
The beige base colour and polished glass reflections provide an appealing foundation for warm turquoise to green-blue.
Grout effect: Matching tones preserve a calm, sandy character.

Caribbean 08
Sea-blue polished glass adds aqua more directly, making the water appear more colourful.
Grout effect: Light grout adds freshness; matching grout creates a more continuous colour surface.

Intense medium and deep blue
Blue and teal pool mosaics enhance water's naturally cool appearance. The darker the lining and the deeper the pool, the richer and calmer the blue appears.

Bluestreak 19
Dark blue polished glass supports a clear, rich pool tone with shifting reflections.
Grout effect: Matching tones soften the grid and give the surface greater depth.

Deep Sea
Sea blue and glossy depth of colour create a classic, balanced water palette between blue and teal.
Grout effect: A similar shade of blue makes the surface feel more expansive.

Cobal
Dark blue Smalto and a metallic-finished backing create sparkling reflections that change with the viewing angle.
Grout effect: Subtle dark grout keeps the colour effect in the foreground.

Emerald and lagoon tones
Green mosaics deliberately give a pool the character of a lagoon, emerald water or a natural lake. Vegetation and shade can intensify the green further.

Mermaid 17
Light green polished Waterglass is a design choice for a bright aqua and lagoon effect.
Grout effect: Light or gently green-tinted grout creates lightness and a soft grid.

Emerald 2
Vivid green and the distinctive textured, glossy Smalto surface create expressive, natural depth.
Grout effect: Matching tones create emerald calm; neutral grout makes individual tesserae more visible.

Grey, silver and a modern infinity-pool look
Grey pool tiles respond particularly sensitively to the sky and architecture. Depending on the light, they appear silvery, grey-blue or slightly greenish. This complements concrete, natural stone and crisp infinity edges.

Mud
Grey Natural glass mosaic creates an understated base that gives reflections and the surroundings room to show.
Grout effect: Matching tones create calm architecture; lighter grout gives more definition.

Titanium 2
The grey Smalto shade combines a modern colour temperature with a lively, textured and glossy finish.
Grout effect: Medium grey gives a continuous appearance; a darker tone emphasises the grid.

Very dark pools and reflective water
Anthracite and black reflect less light from the pool floor. This makes depth and reflections of the sky, trees and architecture more prominent. The water surface looks dramatic, though not necessarily black.
SICIS® · Waterglass
Black
Solid black glass tiles with a smooth, polished surface support depth and clear, shifting mirror-like reflections.
Grout effect: Dark, matching tones create the most continuous surface possible.

SICIS® · Murano Smalto
Black
The textured, glossy Smalto structure gives a dark pool more material presence and breaks up reflections more vividly.
Grout effect: Dark grout creates calm reflections; slightly lighter grout reveals the mosaic pattern.
Discover Black Murano SmaltoConsider light, depth and surroundings
On steps and in very shallow areas, the mosaic's own colour remains more visible. From approximately 1.2 to 1.5 metres, the water colour becomes noticeably more intense; deeper areas look darker. Midday sun brings out lustre and colour, while shade softens them. Blue sky, green plants, light terraces and dark façades are also reflected. Pool shape, overflow edges and underwater lighting change perception too. Never decide solely on the basis of a single dry tessera. Assess a sample area with the intended grout and lighting conditions.
An often underestimated design element
Grout colour and joint pattern
With small-format glass mosaic, grout occupies noticeably more visual space than with large tiles. It helps determine whether the surface appears calm, bright or graphic. This is especially relevant with transparent, iridescent and highly reflective tesserae, as light and adjacent colours also shape the effect of the glass.
Matching tones
Soften the grid and make turquoise, blue, green or grey appear more uniform and continuous.
Light grout
Can brighten the surface and define individual pieces more clearly, without guaranteeing a particular water colour.
Darker grout
Adds definition and depth. In dark designs, it can make the surface appear more continuous.
Mosaic, grout, light, water, depth and surroundings must be considered together. According to the manufacturer, Litokol Starlike® Pro offers 75 shades for joints 1–20 mm wide. This epoxy resin gel is resistant to water, stains and UV exposure and is specified for mosaics.
Design meets the installation system
Why glass mosaic has a distinctive effect in pools
Small tesserae follow curves, steps and seating benches, while glass reflects, concentrates or, depending on the surface, scatters light. Lustre, colour shifts and iridescent effects stay lively even across large surfaces. Technically, however, the entire system matters.
- For permanently submerged areas, the mosaic, backing, substrate, waterproofing, adhesive and grout must be approved together and installed correctly.
- Water absorption, chemical resistance, frost exposure and bond strength must be checked for the specific project. Walkable surfaces also require the appropriate slip resistance.
- The Tiamont pages for the Waterglass, Natural and Murano Smalto variants mentioned specify pool and underwater use when correctly installed. Cobal is described for pool surfaces. Final suitability for the pool type and water treatment should be technically confirmed before ordering.
A brief answer
The key questions about pool colour
Which pool tiles make water turquoise?
Light white, cream, sandy and beige shades, along with bright aqua mosaics, can encourage turquoise. Sunshine and light surroundings enhance the effect.
Which pool colour looks particularly blue?
Pale blue creates a fresh effect; blue and teal a richer one. Greater depth intensifies and darkens the shade.
Are dark pool tiles a good choice?
Yes, if you want reflections and architectural depth. Visibility, lighting, safety and the maintenance plan should be considered early.
Which grout colour suits glass mosaic?
Matching tones look calm, lighter grout feels airier and darker grout looks more graphic. Assess the combination on a grouted sample area under the intended lighting.
