+# Color Chooser Dialog
+
+This library includes a color chooser implementation, which wraps a Material Dialog (that uses a custom view)
+inside of a Dialog Fragment. This means the dialog will survive orientation changes.
+
+The color chooser dialog is used like this:
+
+```java
+boolean accent = false;
+int preselection = // ...
+
+// Accepts an AppCompatActivity and dialog title string ID
+new ColorChooserDialog.Builder(this, R.string.color_palette)
+    .titleSub(R.string.colors)  // optional title when looking at sub colors
+    .accentMode(accent)  // optional boolean, true shows accent palette
+    .preselect(preselection)  // optional color int, preselects a color
+    .show();
+```
+
+The dialog passed in the `Builder` constructor must implement `ColorCallback`:
+
+```java
+@Override
+public void onColorSelection(@NonNull ColorChooserDialog dialog, @ColorInt int color) {
+    if (dialog.isAccentMode()) {
+        // Accent color selected
+    } else {
+        // Primary color selected
+    }
+}
+```
+
+See the sample project for more info.
