Cream Legbar egg color

I FINALLY got my online auction color chart in the mail

None of the 3 eggs I got today are blue (I knew that )
Two are OAC123 one is OAC81

Hoping to add bluer eggs this summer

My egg color goal is OAC 256 and my dream color is OAC 255

My egg color goal is OAC 256 and my dream color is OAC 255

Whoo Hooo -- OAC 255 -- That would be a dream. I would be happy to reach OAC 256. Even OAC235.

Even OAC 207, OAC213 or OAC 214. We can sure dream can't we? -- I guess I'm pretty lucky because I match OSC 179 and
OAC 151, to my eye.....occasionally an OAC 123.

When I pick up one that looks exceptionally blue I check it with a phone APP that detects the color using the phone's camera. It is called -- color detector...and it is free - It works on android devices -- I don't know about the I-phone world.

It is called 'Color Detector by Mobialia'. Free download in the app store if it is still there. SPEAKING of still there -- congrats on getting an OAC, because I didn't think that they even MADE them anylonger.

The phone app gives a lot of information when it reads a color. It isn't BLACK & WHITE -- because color has so many influences. What part of the wavelength is captured at the second the shutter is snapped for example, and what things influence the color detection such as flourescent lights, sunlight, incadescent etc. -- I usually take several readings and they are usually a bit different. - but adjacent, and the human eye - probably couldn't really detect the difference. It gives a hex number (computer talk for color) -- and that can be looked up on the computer.

Here is an example.

I just did a shot of OAC 179 - dark cloudy sky indoors by north facing window and it read me this:

"Submarine / Blue
HTML #8e9796
R 55% G59% B58%
H:173o S:6% V:59% "

Way way TMI (too much information) I know unless one wants to be a colorologist.... but I take that HTML number and plug it into a website and get the color on my screen that I can share with someone remotely. -- The color names are a bit arbitrary and a female voice names the names. The important thing is if it says it is a 'green' or a 'blue' or a 'gray' -- but even more important perhaps is that it tells the percentage of Red Green and Blue that the light waves are. So in this case the G (green) is 59% and the B (blue) is 58%.

but it called it a blue. which I think is pretty cool.

Here is that hex number at the 'color hex' website:
http://www.color-hex.com/color/8e9796

If you go there the top swatch shows the saturated coloration (to the max) -- but if you go down the page there is a row of 'shades' and 'tints'.
The shades are black added and the tints are white added. There are 10 boxes of tints -- and I am beginning to think that the S:6% -- indicates the amount of saturation of that color. so if each of the 10 boxes represents 5% (giving the other 50% of color to the shades) -- then a 6% saturation would put the color in the second color swatch from the right (excluding the last one that is pure white -- and the last one of the shades is pure black.

So that is what my phone detected in the light on OAC 179 - influenced by my windows and the reflected light in the room here -- (there is a lot of green in here and some reds too -- so things seem a bit greener -- out doors is a bit clearer colors. Direct sunlight on the object tends to blow out the coloratin though)

Isn't that just the most fascinating piece of trivia for the day?
Comparing my hex screen side-by-side with OAC, the colors are grayed down -- but it is a pretty deep cloudy day -- so maybe that is to be expected with a detector.

Speaking of that -- they say that egg color never changes -- but I think that is slightly inaccurate. I think perhaps the greenest time is at the beginning of a clutch - or when they first come out of molt. I think that as they continue to lay they loose some of the green. I also think that diet can have some effect - and extra carotenoids may add blue -- and remembering those are fat-soluable I wonder if some extra fat -- would help them metabolize them, I never tried that -- like some wheat germ oil or wheat germ in their feed. hmmmm

The color changes may be so slight that the 'naked eye' can't detect them.

Did you ever read this article?

https://books.google.com/books?id=r...&q=blue footed booby - egg shell blue&f=false

...." for example, in blue-footed boobies, the eggshell color declines with laying order. However, those females that were carotenoid-supplemented after laying their first egg laid a second egg with enhnaced coloration compared to control females."

It's under 6.2 on page 191 - it refers to the 2011 Morales study.

Here's a link to the Moreales study:

Also just for fun - here's a picture of 4 blue-footed booby eggs:

After I read this - I wondered about the color spectrometer:
...."egg color was measured with a CM-2600d portable spectrophotometer (Minolta Co. Ltd., Osaka, Japan)."

so expensive that you have to request a quote

and that is one reason I think the free phone ap is pretty clever.

I don't find that app on the Apple Store
I found one similar but it does not work well and has a lot of spam built in

That is such a shame. Hate apps that fill up with advertising. It's kind of fun to use. I think because it contains variations it makes some super-precise minded people go insane. If I come across anything that is similar I will let you know. I'm not sure if this one is even still available on Android devices..... Do you by any chance have a tablet as well as a phone?== Like a Nexus 7 or a Nexus 10?

Here's an example of how colors can 'change' -- all 3 photos are the same 3 eggs

Can you please tell me how you obtained this chart? Thanks!
