The front tire is orange.

Yup still mostly blue

Are you at all colorblind, or does your camera have a blown sensor, because in these pictures thats a dark blue with maybe a little wash of green under it

It must be the camera. Because in real life it is very green. Like pond scum green. It’s an iPhone 8. It should be OK-ish? Let me bust out the 5d mk2
I will ask my girlfriend. This is exactly the shade of blue she might agree is green. She has high color acuity and some kinda synesthesia, so when I say stuff like 'my black button up’s she’s like »Black? it’s dark blue.«

Color is subjective, I see a blue with green in it, some would see a green with blue in it. If you like the color of a shitbox old mixte mtb hybrid that’s what matters.

Yes, you must be referring to someone else because the bike pictured is a shitty blue-green step through hybrid frame and not a mixte

Color perception is subjective. Color is objective and can be measured.

What I don’t understand is the screen of the phone shows blue and the bike is green. I adjusted the warmth to what the color actually is
And here’s the same picture taken with the Palm Phone
Fix yr white balance
It’s still blue

I once fixed up a Univega of similar vintage that I suspect was the same color.
Whatever it is.

Well, you can measure subjective quantities too.
Wavelengths and distributions of light are physical phenomena, as are surface reflectance, opsin absorptance functions and so on. But those are not colors. Colors, meaning the things you call “yellow”, “red,” etc., are phenomena, in the Kantian sense – things as they appear to your awareness. I try not to use the word “color” when I’m talking about a wavelength distribution or a surface reflectance function.
Commonly used colorimetric spaces and measures are based on correlating wavelengths of stimuli against judgements taken by human observers under controlled conditions, using a shockingly small number of observers. Which is to say, purportedly “objective” colorimetric measures are fundamentally based on an attempt to measure subjective quantities.
Most colorimetric spaces are actually only based on asking human observers whether two stimuli are the same or different, rather than asking them to name colors. If you ask people to name or select pure colors, it turns out that the boundaries of “green” and “blue” are pretty variable between observers.
Phenomena of color constancy (colors still looking similar under different color temperature lamps) suggest that the visual system is trying to estimate the surface reflectance of objects. But this is strictly impossible to do because we don’t know the illumination – the visual system to guess the overall illumination too. In this scene the bike frame is in shadow but set against a background that is in sunlight. This is problematic because illumination in shadow is generally much bluer than in sunlight (due to the blue components of sunlight being scattered in the atmosphere). So what color you see this as will depend on what your visual system is estimating as the illuminant, and that will vary from person to person (remember “the dress”?)

No, keep going. The primate visual system is fascinating.

I occasionally do a short lecture series on microscopy, digitization and image processing. I spend most of the first session talking about the primate visiual system, its features and bugs.
