Re: Eye popping Purple and Yellow Flower on a green background
Brian - it might be an issue with the way your hosting service is working, but when I examine the shot in detail, the green and blue channels show a lot of crushed shadow detail. Looks like an exposure issue.

Re: Eye popping Purple and Yellow Flower on a green background
Brian, some of the 'pop' is perhaps being taken away by the background. The reason is that the background, being green, has much more luminance than the flower details. A luminance histogram will tell all with a big hump in the middle and the flower stuff well over to the left.

An adventure would be to change the background color to blue, because:
Luminance = 0.3red+0.6green+0.1blue ...

Re: Eye popping Purple and Yellow Flower on a green background
the histogram I ended up with is the one you found. The flower is very high contrast in the shade and this was taken in the sun. Except for the bg the colours are close to real. Originally Posted by Manfred M

You have no idea how much I tuned the luminescence down. Let me consider this blue bg idea. Originally Posted by xpatUSA

Re: Eye popping Purple and Yellow Flower on a green background
For me the three colors are too equally intense, I would toning down the least natural one or the one that could easily be seen in nature at different tones.
