Vandaceous Blue, bluest and lightest coloration?
 

So, I am really employing the AI ChatBot to gather info lately! lol

It tells me, that The Vanda Coerulea is known as being the Vandaceous Orchid with the bluest, lightest coloration. I would be interested in any second opinions, whether agreement with AI, or suggestions of other varieties which might rival it for having the "truest blue", whether light or dark.

:thanx:

It's not blue, it's purple. If you want true, sky blue in Vandaceous orchids, check out the genus Cleisocentron.

Again, thank you! How does the blue of the Cleisocentron compare to the Lioulin Blue Novelty Phalaenopsis?

The only orchids with color similar to the transgenic Phal (which contains the "blue" gene of a completely unrelated non-orchid plant) are some of the Thelymitra.http://orchidcentral.org/Images/Disa...tra%20nuda.jpg The Cleisocentron blue is more of a light blue-gray sometimes with a hint of green. Like this: http://orchidcentral.org/Images/Vand...rrillianum.jpg or this: http://orchidcentral.org/Images/Vand...gokusingii.jpg Color in Clctn. merellianium and Clctn. gokusingii is affected by temperature - when they bloom in the winter, colors are more saturated than the summer blooms that are more blue-gray.

ChatGPT scans what's written on the Internet and regurgitates it. It can't make comparisons nor judgments. It's a very fast search engine.

have a look at this one, it comes in various different colors but the bluest of them might be due to darker backgrounds and the lighting making it appear more blue. I have seen a very blue one and although it's a combination of blue and purple I think it can be bluer than the vanda coerulea which is more of a dark purple

Vandachostylis Lou Sneary

Hard to tell from a photo... there's a tendency for people to tweak the "blueness" in the photo, background and lighting are factors but so is post-processing. It's really a dark coerulea... there's violet in there, so a saturated blue-violet. I have seen some really dark Lou Snearys in the "flesh", very bluish but compared to a Thelymitra, not quite - still more blue-violet. Another one with similar, very beautiful blue-violet color is Vandachostylis (Darwinara) Charm 'Blue Pacific'. The limiting factor, no matter how much breeding is done, is that a truly blue gene just doesn't exist in most orchid genera. (Thelymitra is an exception, the majority of species are blue). That genetically-modified Phalenopsis utilizes a gene from the Asiatic Dayflower (Commelina)

I gave up trying to photograph those few true blue (not coerulea) species in anything except for natural light. (My Thelymitra and Cleisocentron photos are unprocessed with regard to color, all I did was crop them) No matter how hard I tried, could not get the white balance correct with artificial light to get the photograph to show what my eyes see. Harder to photograph even than red, which is also really difficult to get right (meaning "what the eyes see")

Look into Vanda Rothschildiana (V. coerulea x V. sanderiana).

I think the white from the sanderiana really muted the purple of coerulea to being pretty darn close to blue.

The only "blue" Vandaceous orchids I know of are:

Cleisocentron gokusingii (as was mentioned, light blue with some green tinges)
Cleisocentron merrillianum (as was mentioned, light blue with some green tinges)

Maybe depending on how you look at them:

Rhynchostylis coelestis

Vanda coerulea (closest to blue)
Vanda coerulescens (somewhat close to blue, but not quite)
Vanda lilacina (white sepals and petals, lilac lip - a bit of a stretch I know)
Vanda tessellata (there is a dark violet version)
Vanda testacea (yellow sepals and petals, lilac lip - again, a bit of a stretch)

Just naming species, too many hybrids to mention, but a couple that stick out are:

Neostylis Lou Sneary

Vanda Princess Mikasa (blue)
