There are functions in skia for creating a color from a specific argb. Can you
use it?

+  // Pack colors according to the order of alpha and rgb
+  return (a << SK_A32_SHIFT) | (r << SK_R32_SHIFT) |
+         (g << SK_G32_SHIFT) | (b << SK_B32_SHIFT);
+}

   const SkBitmap* bitmap = image.ToSkBitmap();
 
   SkAutoLockPixels auto_lock(*bitmap);
   uint32_t* pixel = bitmap->getAddr32(10, 10);
-  EXPECT_EQ(SK_ColorRED, *pixel);
+  // Expect the red color
+  EXPECT_EQ(SetPackedColor(0xFF, 0xFF, 0x00, 0x00), *pixel);
