The Gamma Custom Theme Setup Guide

Follow these six steps to institutionalize your corporate design kit in Gamma:

  • ** Toggle 'Lock Theme' to prevent non-admin team members from altering core font weights and color palettes during presentation generation.

Do This in Gamma

Gamma's workspace theme system bridges generative speed with design governance:

  • ** Once a custom theme is designated as the workspace default, every new prompt-to-deck or document generated by any team member automatically adopts the approved brand kit. This eliminates the 'rogue slide' problem where sales reps use conflicting fonts, distorted logos, or misaligned color palettes. Fit note: The ideal presentation governance engine for scaling startups and modern remote companies.
