Likewise with the hen, I'm not sure what makes you think Royal Palm cross -- because she's light? -- but she looks like a Narragansett hen to me. The extent of white in the Narr hens I've seen has varied quite widely and they do tend to be lighter than the toms. (example: here
There are more Narr pictures on feathersite that may be of help, too.
The tom is kind of dark but they both look very Narri to me. The hen looks just like mine. My toms are not as dark on top of the wing or on the belly, but I think that is jus t natural variation. I have a neighbor with a darker Narri tom. I don't remember if it is as dark as your pictures, though.
