My theory about why observed color of wavelengths varies-
Lasers are unique for our eyes in that they produce a very narrow, constant, frequency band. Both narrow and constant are important.
When ambient light conditions change, our perception changes with them. For example, when our eyes are well adjusted, a white bowl in daylight and the same white bowl under tungsten lighting will both appear white, even though the latter is more orange. However the color of a laser can’t change (since it is light itself), and it is a narrow enough band of light for us to notice (unlike colorful lamp or LED). So for instance, when we transition from daylight to tungsten lighting, a 580nm that seemed a lemon-yellow color outside will now appear a golden 589 color, because it is “stuck” at its true color, 580nm, while your eyes have adjusted to a warmer light by adding blue. And finally, this effect is magnified in the parts of the visible spectrum that change color quickly with change in wavelength, such as yellow-green and cyan.
Edit- I’m still thinking about the accuracy of my example. I should actually try this to confirm, just a hypothesis right now. Gets confusing thinking about all the opposite blue/orange shifts and what stays constant and what doesn’t. But you get the idea
