    On the picture it is dark cyan, which would be consistant with a dark grey paint reflecting the sky color.

    now this is grey in similar weather

    It turns out there are many shades of grey (way more than 50), along with any other colour...fancy that?!

    Yeah. Which proves that it makes the most sense to call the H6 white.

    You think that you are being all objective and sensible by just saying what color it most looks like to the naked eye in this one. So you say dark grey. But when it comes to the H6, you do the opposite. Clearly in the pic in the bright sky, the H6 looks white.

    And 2001 doesn't look dark grey. To the naked eye, tt looks matte black. Like this

    It does look matte black with an ever so slight tinge of dark green in there. Like this except 50% less green in it

    The light in a Cloudy weather is even more blue because the red and yellow light from the sun is filtered by the cloud layer.

    The perceaved color of a object is the product of 3 functions:

    1- the spectrum of the illuminant (which can be a mix of primary and secondary sources)
    2- the spectral reflectance of the object (the "color" you are looking for)
    3- the sprectral response of the observer (camera sensor or human eye)

    Then the brain or the Image signal processor must perform a white point to neutralize the whites (this requires the aptitude to recognize white or grey objects is the scene).
    This can be very complicated because you can have grey objects illuminated by different light sources in the same scene.

    Anyways, what you are asking for, is the spectral reflectance of the J-20's paint (a perfect neutral grey would be a flat curve with the same reflectance for all wavelengths of the visible spectrum).
    This is impossible to know from a picture because you don't know the 2 other functions nor how the camera did its white point.

    If you want to know the "real color" (ie the spectral reflectance) of an object you need a calibrated source and a calibrated spectrometer like this guy :

    You seem to be knowledgeable in this domain. What color would you say it is ?

    Fine ... at least not DARK green and WHITE.

    My working week and my Sunday rest,
    My noon, my midnight, my talk, my song;
    I thought that love would last forever; I was wrong.

    The stars are not wanted now; put out every one:
    Pack up the moon and dismantle the sun;
    Pour away the ocean and sweep up the woods:
    For nothing now can ever come to any good.

    Yeah. He kinda admitted that the color is in the green family. So I think we have to give you the win on this one.

    If You would read properly I always admitted that it has a greenish shine in certain lightning conditions but at least by my perception, green is grass, green is the colour of the C919's tail and YES for sure, olive is a shade of green, IMO olive is OLIVE and not true GREEN in the same way turquoise surely has also a certain content of green, but is more a bluish green than true green.

    Maybe we could do some sort of colour check by mentioning the exact wavelength ?

    Try it again; I know You can even if a bit difficult, but I said:

    IMO olive is OLIVE and not true GREEN in the same way turquoise surely has also a certain content of green, but is more a bluish green than true green.


    I even highlighted for You the important part in case You miss it again.

    thanks! but unfortunately I hate to burst your bubble but Ripe Olive is dark green.

    the official explanation based on
    http://encycolorpedia.com/474c42

    says

    The hexadecimal color code #474c42 is a medium dark shade of green. In the RGB color model #474c42 is comprised of 27.84% red, 29.8% green and 25.88% blue. In the HSL color space #474c42 has a hue of 90 degrees, 7.04% saturation and 27.84% lightness. This color has an approximate wavelength of 563 nm. Sherwin-Williams Ripe Olive - 6209 is a matching paint color.

    whatever it is, it is definitely not a pure grey.

    Thanks for that scientific explanation; and YES by that standard I have to admit ... but like You added in Your last post: whatever it is, it is definitely not a pure grey.

    Below image is the most greenish looking photo. So Depends on the lighting conditions:

    Using simple web colors - https://www.w3schools.com/colors/colors_groups.asp

    It looks close to the DarkSlateGray - https://www.w3schools.com/colors/col...olorhex=2F4F4F

    But remember these are RGB colors used for your computer display (Additive colors). When it comes painting/printing subtractive color models are used.
