Lightbox: Custom Colors

1 min read

Updated May 20, 2026

When the Lightbox Theme is set to Custom, every color in the Lightbox can be defined individually. Colors are organized into five groups — General, Toolbar, Navigation, Thumbnails, and Info Panel — and the Custom Theme section only appears when Custom is selected.

Tips #

All colors accept any CSS color value — hex, RGB, or RGBA. Use RGBA to control transparency, which is especially useful for the backdrop and toolbar background.

The Dark and Light built-in themes use these same color properties internally. Switching to Custom gives full control over the same set of tokens. If you only want to change one or two colors, switch to Custom Theme and match the remaining values to the dark or light defaults listed above.
