Brian,
Have you played with WB, it might affect your greens but if lean towards blue or red you might get something a bit closer.
This is lilac color; nice color
Very nice, great colour.
I have similar problems with the purple flowers of Duranta erecta (Geisha Girl) and verbena. A macro shot uncovered the reason for my problems; the petals have a very fine coating of coloured hairs and if the lens can't resolve them the colour of a photo never turns out to be what I see. Then again maybe I need specs.
if "Popping" means making it stand out, not getting the right color, then look at Ziggy's latest. The key may be a color theory problem. Purple will stand out against its complement--yellow.
It seems good to me Brian,a very nice colored flower
Purples and magentas etc are always tricky, Brian. You have made a good job of avoiding over saturation while keeping the scene bright.
These colours change depending on the light angle and intensity so I always find editing tricky; which is why I set a Custom WB check before shooting. I have even picked a flower and taken it indoors to compare directly against my computer screen; but as soon as I took it inside the colour 'changed' to a different shade!
The HSL sliders can be useful when trying to manipulate specific colours.
