I always hear about blue-light filtering software or glasses people use to benefit their sleep cycles. Blue light seems to have a lower wavelength than both red and green and if color combinations behave linearly, blue would have the lowest of the combinations of RGB. Does this contribute to blue light having a negative effect on sleep cycles?

Blue light can suppress the production of melatonin, hence effect on sleep cycles. It might be more related to our body's mechanisms.

If we shift the primary lights, can we still represent so much colors in different wave length?

Though the computer/phone screen is assumed to be a significant source of blue light, the largest source is the sun, however. And it is still controversial that if the blue eye glass could effectively block the blue light. Source: https://www.aao.org/eye-health/tips-prevention/should-you-be-worried-about-blue-light

The most interesting aspect of this tirstimulus theory to me is that we start by defining an object's color in terms of its spectral power distribution (a function of wavelength, i.e. an infinite dimensional vector). But now, we can define any human-perceptible color as a linear combination of three primary colors (i.e., a three-dimensional vector). In doing so, we have infinite dimensions to only three dimensions. This also means that there should be a large kernel/nullspace in this transformation, so even if several objects are perceived as having the same color, they can actually have very different spectral power distributions!

I am just curious but is there names for the colors that require negative red light to achieve? We probably won't be able to see it, but was just wondering if there are color codes/color names for the whole space of r, g, b wavelengths
