Themes

Light and dark, across the whole surface.

Switch the entire chart between a dark and a light theme. The change applies to candles, axes, overlays and tool output together, so nothing looks out of place.

What changes

Chart background, gridlines and axis labels.
Candle and overlay colors adapt for contrast on the chosen background.
Tool results and drawings remain readable in both modes.

Tip: Dark is easier on the eyes for long sessions and makes glowing signal markers pop; light is better for screenshots, print and bright rooms.
