If you are building an underwater base in Minecraft, the block palette you choose makes the difference between a base that looks like it belongs there and one that looks like a box dropped into the sea. The Update Aquatic, released for Java Edition on July 18, 2018 as version Java Edition 1.13, revamped the oceans and added many new aquatic blocks, items, and structures.

This update gave builders a treasure trove of ocean-themed blocks that are perfect for underwater builds. Below are the best block palettes for underwater bases, from classic ocean monument inspired to modern and organic.

## Classic Ocean Monument Palette

The most natural choice for an underwater base is the palette used by ocean monuments themselves. The monument is constructed entirely from variants of prismarine and lit by sea lanterns.

This palette is timeless and looks incredible in any ocean biome. Use prismarine bricks for the main walls, dark prismarine for accents and trim, and sea lanterns for lighting. The dark teal and cyan tones blend perfectly with the water color, making your base feel like a natural part of the ocean. Add prismarine stairs and slabs for detail work and pathways.

## Weathered Copper and Prismarine Blend

For a more organic, aged look, combine copper blocks with prismarine. Copper oxidizes over time from a bright orange to a weathered green, which pairs beautifully with the blue-green tones of prismarine. Use weathered copper for roofing or accent walls, and dark prismarine for the foundation. Sea lanterns provide warm light that complements the copper's rust tones. This palette works especially well for bases built into ocean cliffs or near shipwrecks.

## Vibrant Coral and Warped Wood Palette

If you want your underwater base to pop with color, use warped wood and coral blocks. Warped planks and stems have a striking cyan color that stands out against the deep blue of the ocean. Pair them with coral blocks in red, pink, yellow, and blue for accents. Use sea lanterns or froglights for lighting – their warm glow contrasts nicely with the cool tones of the warped wood. This palette is perfect for a base that feels alive and otherworldly, like an alien coral reef.

## Modern Quartz and Concrete Palette

For a sleek, modern underwater base, use white quartz, light gray or white concrete, and glass. This palette creates a clean, minimalist look that feels like a luxury underwater villa. Use sea lanterns hidden behind the glass or under slabs for a soft glow. Add dark prismarine or blackstone for contrast in floors or trim. This palette works best in warmer ocean biomes where the water is clear and bright.

## Essential Building Tips for Underwater Bases

No matter which palette you choose, follow these tips to make your base functional and safe:

- **Lighting**: Place sea lanterns, froglights, or glowstone every 10 blocks to prevent drowned from spawning inside your base.
- **Conduit Power**: Activate a conduit using prismarine related blocks to get underwater breathing, night vision, and faster mining.
- **Bubble Columns**: Use soul sand to create upward bubble columns for quick ascents, and magma blocks for downward columns.
- **Air Locks**: Use doors, trapdoors, or bubble columns to create air locks so you can enter and exit without flooding your base.
- **Sponges**: Clear water quickly with sponges, which can be found in ocean monument sponge rooms.

## Frequently Asked Questions

**What is the best block for underwater bases?**
Prismarine bricks are the best block for underwater bases because they match the ocean aesthetic perfectly and are naturally found in ocean monuments. They also have a full set of stairs, slabs, and walls for detailed building.

**Can I use wood in an underwater base?**
Yes, you can use any wood type underwater. Warped wood and dark oak are popular choices because their colors contrast well with the water. Just make sure to light your base well to prevent mob spawns.

**How do I light an underwater base without breaking the aesthetic?**
Use sea lanterns for a natural ocean look, or froglights for a warm glow. You can hide them behind glass, under slabs, or inside walls. Glowstone also works but has a more yellow light.

**Do I need a conduit for an underwater base?**
A conduit is highly recommended because it gives you water breathing, night vision, and haste, making building and exploring much easier. It also attacks hostile mobs nearby.

**What blocks should I avoid underwater?**
Avoid using blocks that break easily with water flow, like dirt, sand, or gravel, unless you plan to support them. Also avoid blocks that are affected by gravity, like sand and concrete powder, as they will fall down.
