Android 系统设有 Light Mode 和 Dark Mode 让不同用家选择，而个别应用程式一般亦会对应系统的默认模式作显示，又或让用家自行选择 Light Mode 或 Dark Mode。
早前外国有部份用家发现 Google Assistant 接口只以 Dark Mode 显示，就算 Android 系统选用了 Light Mode，但 Google Assistant 仍是 Dark Mode。Google 近日就公布 Google Assistant 只会提供 Dark Mode，不会有 Light Mode。
Google 人员在 Google Assistant Help Page 表示，Google Assistant 会不断测试以作改进，为了统一产品在不同装置上的外观一致性，之前 Google Assistant Light Mode 不会再提供，并会变成 Dark Mode，就算电话内将 Dark Mode 关闭，Google Assistant 仍会以 Dark Mode 显示。
Google Assistant regularly tries new ideas to see what works and what could work better. This includes ways to make our products look and feel consistent throughout our product ecosystem. To offer a more helpful visual experience across all your devices, including Pixel Watch and Google TV, when you engage with Assistant on mobile Light mode is no longer available – it will now have a dark appearance, even if you have Dark theme turned off in your phone settings.
