Agree Derek, very cool colour renditions indeed - dose the Ra have a fine colour adjustment on them ?
I know my old 600D and the newer 'but still a bit old to most' 6DII have, that quad-cross grid where can add or substract colours in increments.
I usually set for landscape for landscape but then add a couple of notches of blue & green in the quad-grid, can use onboard saturation but that increases all colours.
I used to bump up the red whilst killing off some blue when the dslrs in a scope too - depending on white balance speshly with the older 600D, the 6DII has the kelvin setting which is real nice
