+#### <sup>1)</sup> ANSI Color Generation
+
+> [!NOTE]<br>
+> These bright colors are not necessarily "brighter" than the normal colors, but rather more bold and saturated.
+
+The ANSI brights, excluding `black` and `white`,  are automatically generated based on the following formulas:
+
+<table>
+  <tr>
+    <th>Mocha, Macchiato, Frappé</th>
+    <th>Latte</th>
+  </tr>
+  <tr>
+    <td>
+<pre><code>color.lightness * 0.94
+color.chroma + 8
+color.hue + 2</code></pre>
+    </td>
+    <td>
+<pre><code>color.lightness * 1.09
+<br>
+color.hue + 2</code></pre>
+    </td>
+  </tr>
+</table>
+
+The color values for `black` and `white` are mapped as shown below:
+
+<table>
+  <tr>
+    <th>Mocha, Macchiato, Frappé</th>
+    <th>Latte</th>
+  </tr>
+  <tr>
+    <td>
+      Black (0): <code>Surface 1</code><br>
+      Black (8): <code>Surface 2</code><br>
+      White (7): <code>Subtext 0</code><br>
+      White (15): <code>Subtext 1</code>
+    </td>
+    <td>
+      Black  (0): <code>Subtext 1</code><br>
+      Black  (8): <code>Subtext 0</code><br>
+      White  (7): <code>Surface 2</code><br>
+      White (15): <code>Surface 1</code>
+    </td>
+  </tr>
+</table>
