Might there be a more descriptive name?

+    SkPaint paint;
+    paint.setTypeface(SkTypeface::CreateFromName("Arial", SkTypeface::kBold));

Is there a particular reason you chose this font? Do we have any fonts that
would look the same across platforms?

+    canvas->clear(SK_ColorLTGRAY);
+    paint.setColor(SK_ColorRED);
+    canvas->drawText("R", 1, 8.0f, 20.0f, paint);
+    paint.setColor(SK_ColorGREEN);
+    canvas->drawText("G", 1, 24.0f, 20.0f, paint);
+    paint.setColor(SK_ColorBLUE);
+    canvas->drawText("B", 1, 40.0f, 20.0f, paint);
+    paint.setColor(SK_ColorCYAN);
+    canvas->drawText("C", 1, 56.0f, 20.0f, paint);
