Base Map Layers
Choose and customize the background map for your interactive map.
What is a base layer?
The base layer is the background tile map that appears behind your markers and data. It provides geographic context — streets, terrain, satellite imagery, or a minimal design.

Visual effects and filters
Adjust the base layer appearance with CSS-like filters to match your design:
| Filter | Range | Default | Description |
|---|---|---|---|
brightness |
0–200 | 100 | Lighten or darken the map |
contrast |
0–200 | 100 | Increase or decrease contrast |
saturation |
0–200 | 100 | Adjust color intensity. Set to 0 for grayscale. |
hue |
0–360 | 0 | Hue rotation in degrees |
invert |
0–100 | 0 | Invert colors. 100 = fully inverted. |
opacity |
0–100 | 100 | Transparency. 100 = fully opaque. |
Common recipes
Grayscale map
Set saturation to 0. Works with any base layer.
Muted background
Reduce saturation to 30–50 and increase brightness to 110–120. Creates a subtle, brand-friendly background.
Dark mode
Use the Carto Dark Matter layer, or invert a light map by setting invert to 100.
Subtle base
Reduce opacity to 50–70 for a faded background that lets your markers stand out.
Plan availability
Base layer editing requires the Pro or Enterprise plan. The Free plan uses the default OpenStreetMap layer.
