Gamma

Gamma maintains brand consistency across presentations, documents, and websites through a centralized theming and brand system. This system allows users and organizations to define a cohesive visual identity that can be applied uniformly to all content created within the platform. The core of this functionality is the Theme Editor, where users can either customize one of Gamma's pre-built 'Standard' themes or create a new theme from scratch. This centralized approach ensures that all outputs, regardless of format, adhere to the same set of visual guidelines, reducing the manual effort required to maintain brand alignment across different types of collateral. The system is designed so that a single theme can be applied seamlessly to a slide deck, a multi-page document, or a published webpage, all originating from the same core content. Within the Theme Editor, users have control over several key elements of brand identity. For typography, the system allows the selection of specific fonts for both headings and body text, with granular adjustments for line height, letter spacing, and base font size. A critical feature for brand consistency is the support for custom font uploads, enabling organizations to use their proprietary typefaces. The color palette can be precisely defined using hex codes or a color wheel for various elements, including backgrounds, buttons, links, and text. The system also allows for the configuration of design and layout details such as card styles (e.g., sharp vs. rounded corners), strokes, and shadows. For asset handling, logos can be uploaded and positioned in one of the four corners of the content. Users on paid plans, such as the Pro tier, can integrate logos into headers and footers for persistent branding. Furthermore, themes created within a workspace are automatically shared with all team members, promoting consistent usage across an organization. Users can apply these themes globally to a workspace or on a per-project basis. When compared to other platforms, Gamma's brand system has distinct characteristics and limitations. Canva's 'Brand Kit,' for example, offers more stringent brand governance. Administrators in Canva can 'lock' brand controls, preventing team members from using non-approved colors, fonts, or logos. While Gamma's 'Teams' plan includes brand controls, the available information suggests they are less restrictive than Canva's, potentially allowing for more 'off-brand' content creation. Compared to a professional web development platform like Webflow, Gamma's system is far less granular. Webflow's 'Style panel' provides CSS-level styling capabilities and supports reusable components, offering a much deeper level of design freedom and tokenization suitable for developers. Gamma, in contrast, prioritizes AI-driven speed and automated layouts over such deep customization. A significant practical limitation of Gamma's brand system is its performance during export. Independent analyses have shown that brand fidelity is often compromised when exporting to PDF or PPTX formats. These exports can result in 'broken' templates with font substitutions, color shifts, and altered spacing, requiring 10-15 minutes of manual cleanup to realign the output with the original brand guidelines. This occurs because Gamma's proprietary, web-native design system does not translate perfectly to the fixed-layout structures of PowerPoint and PDF. In conclusion, Gamma provides a robust, centralized theming system for maintaining brand consistency in content that is shared and viewed online via its native web format. The ability to control typography, colors, and logos from a single source and apply it across presentations, documents, and websites is a key strength. However, the system's effectiveness is significantly diminished when content is exported to traditional static formats like PDF and PPTX, where brand consistency frequently breaks. Furthermore, its brand governance controls are less restrictive than those found in competing platforms like Canva, which may be a consideration for larger organizations with strict brand compliance requirements. The system is therefore best suited for teams that primarily distribute content through live web links.
