there is a cost (albeit small) in JNIfying the array of strings for suggestions
so I'd prefer that they are not added until we really need them. You can send
them all the way from Blink to the browser but not to java if that's ok.

I reimplemented the simple color chooser so I can use the labels as the content
description.

         OnColorChangedListener listener = new OnColorChangedListener() {
           @Override
           public void onColorChanged(int color) {
               mDialog.dismiss();
               nativeOnColorChosen(mNativeColorChooserAndroid, color);
           }
         };
 
         mNativeColorChooserAndroid = nativeColorChooserAndroid;
-        mDialog = new ColorPickerDialog(context, listener, initialColor);
+        mDialog = new ColorPickerDialog(context, listener, initialColor,
+            suggestions, suggestionLabels);
     }
 
     private void openColorChooser() {
         mDialog.show();
     }
 
     @CalledByNative
     public void closeColorChooser() {
         mDialog.dismiss();
     }
 
     @CalledByNative
     public static ColorChooserAndroid createColorChooserAndroid(
             int nativeColorChooserAndroid,
             ContentViewCore contentViewCore,
-            int initialColor) {
+            int initialColor,
+            int[] suggestions,
+            String[] suggestionLabels) {
         ColorChooserAndroid chooser = new ColorChooserAndroid(nativeColorChooserAndroid,
-            contentViewCore.getContext(), initialColor);
+            contentViewCore.getContext(), initialColor, suggestions, suggestionLabels);
         chooser.openColorChooser();
         return chooser;
     }
 
     // Implemented in color_chooser_android.cc
     private native void nativeOnColorChosen(int nativeColorChooserAndroid, int color);
 }
