The Resend team has introduced a new feature called "Resend light mode" to the Resend Dashboard, allowing users to customize their experience with a lighter color palette. This change was made in response to user feedback about dark mode being difficult for some users to use, particularly those who need to collaborate on emails across different organizations. The new light mode is designed to be more accessible and inclusive, while still maintaining the brand's predominantly dark color identity. To implement this feature, the team used Radix Colors and Tailwind, conducting experiments in Figma to ensure legibility and contrast ratios were considered. The transition was made possible by the tech stack, which allowed for a significant portion of needs to be accommodated through importing Radix colors as CSS variables and incorporating these values into the Tailwind configuration.
