Some yellow roses

First picture shows a late bloom from Rosa xanthina held up beside an opening flower on 'Hazeldean'. They're pretty close in saturation of color.

The second picture shows that same Rosa xanthina flower held up beside and opening flower on the Rosa rugosa X 'Hazeldean' hybrid. Rosa xanthina looks a little lighter in this picture but I think it was because the picture was taken in the shade of the house.
