Theme colors help a Google Slides presentation use a coherent palette. Editing the theme’s colors is useful when a recurring accent needs to change across a deck. It differs from selecting one shape and assigning a custom color that only that object uses.
Open the theme controls
On a computer, open the presentation and choose Slide > Edit theme. Use Colors at the top, then choose the theme color you want to change. Google’s theme guidance describes editing an individual color through this theme-level interface.
Change colors intentionally
Replace the selected theme color with a suitable choice. If your organization supplies an approved color value, use it accurately rather than approximating it by eye. Keep a clear distinction between background, text, and accent roles so that a dark accent does not unexpectedly become unreadable against a dark background.
Review objects that use the theme palette and objects with manually selected colors. A manually colored chart label or imported illustration may not respond like a theme-aware element. Do not promise that editing the palette recolors every pixel in an image.
Verify meaning and contrast
Check the presentation in slideshow view, especially tables, charts, and warning callouts. Keep labels or symbols alongside color distinctions so that a status is not communicated through color alone. Compare several layouts before applying further visual changes. If only one decorative object needs another color, edit that object directly; a theme-level change should serve a repeated design requirement rather than a one-slide exception.
