Why Your Pool Finish Determines the Color of Your Water

by Southern Pool Designs | Design & Engineering Excellence

Most people think choosing a pool finish is about how the surface looks in the showroom. The truth is, the finish you choose doesn’t determine how the surface looks, it determines how your water looks.

That’s why at Southern Pool Designs, before we ever show you plaster samples, we start with one simple question:

“What color do you want your water to be?”

Once you answer that, we can guide you toward the right finish to achieve it.


Water Color Comes from Depth, Light, and the Finish Beneath

Your pool water is technically clear. The color you see is light reflecting off your finish, the water’s depth, and everything around it.

When you see a tropical blue, deep lagoon, or emerald green pool, it’s the combination of:

  • Finish color and texture
  • Pool depth and shape
  • Lighting and surrounding environment

Two pools with the same finish can look completely different. The same plaster that looks bright blue in an open backyard may look dark teal under trees or near a darker house.


The Big Misconception: Tan Finish Equals Blue Water

This is where many homeowners get surprised. Everyone loves the warm, beachy look of a tan or sand-colored finish, expecting it to give that “Caribbean blue” vibe.

But here’s what really happens:

  • Tan finishes reflect light with yellow and brown tones
  • That reflection turns the water a soft green or aqua tint instead of bright blue
  • The deeper the pool, the darker and greener that color appears

If you love emerald, natural, lagoon-style water, tan is perfect. But if you want crisp, bright blue, you’ll need a lighter gray or white base. That’s exactly why we guide clients by water color first and finish second.


How to Think About Water Color the Right Way

Here’s how we explain it in the Design Studio:

Desired Water ColorFinish FamilyLook & Feel
Bright Blue / AquaWhite, light gray, or pale blueTropical, fresh, reflective
Medium BlueMid-gray or pebble blendsBalanced, clean, modern
Deep BlueCharcoal, dark gray, deep blueResort-style, high contrast
Green / Lagoon / NaturalTan, brown, or stone-like finishesOrganic, earthy, “Florida spring” look

Once we know the water tone you’re drawn to, we can show you real-world projects with the same finish and lighting conditions. That way, there are no surprises when your pool is filled.


Why Finish Texture and Material Matter

The base color isn’t the only factor. The type of finish changes how light interacts with your pool:

  • Standard Plaster: Smooth and bright, reflects more light for a lighter water color.
  • Quartz or Pebble Finishes: Add depth, sparkle, and durability. Water appears slightly darker and richer.
  • Glass Bead Finishes: Create shimmer and movement, especially under LED lighting.

At SPD, we walk you through samples under real light and show how color changes from shallow sunshelves to deep ends. A 3-foot step and a 6-foot deep end can look like two different pools, so we make sure you understand that before we ever start construction.


How to Choose Wisely

The key is balance. You don’t pick a finish because it looks good dry. You pick it because it looks right wet, under your home’s lighting, deck color, and landscaping.

That’s where our experience comes in. We’ve built thousands of pools across Central Florida and know how finishes perform in every setting from Lake Nona to Viera to St. Augustine.


We Build for Beauty and We Stand Behind It

Once you fall in love with your water color, you can feel confident it will stay that way. Every pool we build is backed by our finish and workmanship warranty, and our service team is always available to handle even the smallest details after startup.

A beautiful finish should stay beautiful. That’s our promise.


Final Thought

Pool design is equal parts art, science, and experience. You can’t guess your way to perfect water color. That’s why we never start with plaster samples. We start with your vision.

Tell us the water color you love, and we’ll reverse engineer everything — finish, lighting, and depth — to make it perfect.
