Dark Mode Considerations:
-
The logo must adapt to dark mode interfaces by switching to high-contrast alternatives.
-
The light version of the wordmark should be used in dark mode, ensuring a minimum contrast ratio of 4.5:1.
-
Icons must be optimized for inverted or light-on-dark settings.
5. Universal Logo & Icon Requirements
(Applies to Both Icon & Wordmark)
File Variants:
-
-
RGB (sRGB): Digital use (web, apps, presentations)
-
CMYK: Print applications
-
SVG/EPS: Scalable vector format for high-resolution applications
-
Padding & Safe Zone:
-
-
A minimum clear space equal to 10% of the logo’s height must be maintained on all sides.
-
No Distortion Policy:
-
-
The aspect ratio must remain intact at all scales. Stretching, skewing, or warping is not permitted.
