Problem with blue flowers

So as many of you have already experienced: "blue" or "blueish" orchids always turn out purple.
I have a vanda pachara delight and a coerulea that I'm wanting to photo when they flower but can't get the true colour.
Has anyone experimented with filter colours or white balance to get a better blue?
I'm interested to hear if anything works.

I'm guessing that I might try a yellow red or green filter.

Any tips are greatly appreciated!

Haven't tried filters yet but digital cameras are a pain to capture "blue flowers". Reds can also prove difficult.
I'm not sure but I think what we see is a spectrum color like that the digital can't. Film cameras worked well. ( user ability to be considered)

I sometime try to place a pot in different places - against the black background, very white background, shooting in the dark with flashlight only, etc.

Sometimes it's a type of camera, the more sophisticated one with a bigger zoom seem to be coming up with more realistic pictures.

If nothing else, I use a Photo editing feature to play with brigthness/contrast/colour range to get that colour I'm aiming at.

This is certainly a challenge!

I read an interesting "how to" and it said that flowers have so many types of colours that we can see, and there is a huge spectrum of lights that we can't see on the flowers, designed to "glow" when insects see it.
Apparently try take the photo when it's overcast as the sun will give too many reds in the light.

But most cameras are designed to filter some of the UV lights that we see on a flower

Can you adjust the red balance once you download it? Maybe removing some red will allow the blue to show through.

Don't go with blue.
Instead of that go with yellow ones.
I have face the same problem but this is due to climate change, nothing else.

Have you tried a polarized filter?

I have found using a white background instead of the usual black helps me get a truer color for my 'blue' orchids and some of those red/magenta colored blooms.
