I recommend looking up the Golden hour and the related Blue hour to see the benefits of photographing then.
At that time there is a soft, yet directional light, which is the best natural light there is to bring out details, open up shadows and avoiding that highlights become overexposed.
A light color such as the blue in Absolute Treasure will essentially look whiter or lighter in harsh midday light. You could take steps to reduce this effect, but the result wont be nearly as good as if you have good light to start with, IMHO.
In my garden the light is even more diffuse in the Golden Hour, because the forest filters all light. You can see in my photo that there is very little shadow under the flower.
This lack of shadow is also influenced by how I processed my image(my RAW file) in post production, because I "opened up" the shadows a bit and reduced the highlights further, but mostly it is because of the quality of light. This all helps to saturate the color.
If you look at the Globemaster Alliums in the background, you can also see that on the left there is a flowering head that is more warmly purple than the rest. This is because it is hit by more direct late sunlight than the rest. There is a difference in color temperature even within the photo. This can also help to bring out the blue in 'Absolute Treasure', because if the background is warmer and the foreground is colder, or more blue, then the color of Absolute Treasure will also look more blue in the photograph.
Remember that all colors we see are based on reflected light, as such there are no true colors, because they will vary with the light.
Go into a room with red light only and enjoy a very red version of Absolute Treasure.
I'm very nearsighted and one eye is better than the other so at one point I stared at me phone screen very closely with one eye only to see some small text better. Afterward I was a bit scared. Opening up my eyes, my brain had adjusted so I had different white balance on my left and right eye. The one looking at the cold blue light from the phone screen now overcompensated and everything was looking overly warm or yellow.
What I want to say with all this is that there are a ton of factors that influence how we experience colors, so comparing from photos will never be 100% accurate.
