    Lume - is it Blue or is it Green

    After posting a lume pic of my explorer on another thread there was a split of opinion whether it looked green or blue.

    So which is it? Does it look green or blue to you. I think it looks blue in the pic but greener in real life. It's a new explorer so should be blue as far as I'm aware.

    Blue. All my Rolex are blue but sometimes they look a bit green esp in photos.

    Blue for me too. But yes, sometimes it looks more green-blue depending on the lighting and camera lens.

    I've also seen green lume somehow look blue in pictures too.

    Like all Rolex, it should have a special nickname - Bleen

    If you use light from your phone is glows more greeny blue and it's natural light it's bluer ( so ) is bluer a word ?

    Are you trying to say the light source that charges the lume makes a difference, or the light source used when taking the photo makes a difference?

    I've read that before too. Natural light makes the lume glow with a bluer light

    Yes its the little source, try it with your phone torch and then the next day on the window sill.

    The torch charge makes it glow greener and the natural light is a stronger blue.

    Why is this still being discussed??

    It's blue FACT, no opinion or discussion needed.

    Light source to charge will be negligable, as most watch lume uses light in the UV wavelength to charge.
    Which is why they charge super fast via a LED torch, or outdoors compared with a bedside incandescent light



    But when it comes to taking photos the ambient light makes a huge difference (or even looking at things with your own eyes)

    Outdoors - you'll get a blue bias (depeding on weather)

    Indoors with incandescent light, you'll get a yellow bias
    Indoor with Flourescent, you'll get more green
    Indoor with LEDs.. blue/or yellow depending on LED Warmth
    In an Amsterdam window, pure red.

    combine that with
    - overal lighting, (less light less easy to distinguish between colors)
    - the cameras sensor IQ and general ability to capture accurate colors
    - a typical digital cameras attempt to Auto balance whites
    - file compression
    - the actual colour balance of the screen the photo is being displayed on

    and the lume could actually be any color but what is being shown on screen

    Not sure the bias you mention will greatly affect apparent colour of lume.

    For example, indoors with incandescent light, yes objects will look yellow by reflection but the lume is actually 'glowing' blue so effect will be negligible. (Though decent camera/phone can compensate for the yellow cast so everything, including lume, will look bluer!)

    There will allways be a bias regardless if the lume itself is glowing (even glowing obejcts will absorb/reflect a portion of ambient light).
    It's all down to how we individually see and separate individual colors, there are plenty of "optical illusions" that show how surrounding one colour, with different colors of the same luminescence value can affect what color we think we are seeing.

    If we then consider the glow of the lume plot itself, the perceived color at full brightness vs half brightness will be different again. There'll be factors like the effect on the lume's pigment on the actual lume color

    IE, say if you covered a blue bulb, with a red lamp filter... turn it up high enough there will be a point where the blue light is no longer being affected by the red, but turn it back down and more blue light is filtered and it will look red.
    you see this every day on cars, with red glass over indicators, they still appear yellow because the there is more yellow light being emitted than the red glass can absorb.
    So the real question that will answer it all, is what is Chromalight's base emissive color before any pigment is added.


    I spend a fair amount of my life staring at colors, pixels, and trying to balance palettes under different lighting conditions, so i know the odd thing about how they work ( or don't work when you need them to, even if its the correct real world HSV/RGB value)

    Yes, I asked for clarification because the idea the source light would make any difference doesn't seem likely.
