+!!! warning "Requirements when using [custom color schemes]"
+
+    The built-in [color schemes] define the aforementioned hash fragments, but
+    if you're using [custom color schemes], you'll also have to add the
+    following selectors to your scheme, depending on whether it's a light or
+    dark scheme:
+
+    === "Custom light scheme"
+
+        ``` css
+        [data-md-color-scheme="custom-light"] img[src$="#only-dark"]
+        [data-md-color-scheme="custom-light"] img[src$="#gh-dark-mode-only"] {
+          display: none; /* Hide dark images in light mode */
+        }
+        ```
+
+    === "Custom dark scheme"
+
+        ``` css
+        [data-md-color-scheme="custom-dark"] img[src$="#only-light"],
+        [data-md-color-scheme="custom-dark"] img[src$="#gh-light-mode-only"] {
+          display: none; /* Hide light images in dark mode */
+        }
+        ```
+
+    Remember to change `#!css "custom-light"` and `#!css "custom-dark"` to the
+    name of your scheme.
