Color of sun blinding effect
I noticed that the sun blinding effect is always white regardless of the sun color. Is there a reason this is so or was it just forgotten?

Re: Color of sun blinding effect
I'm guessing just because it's a bright light. Anything's white if it's bright enough!

Yes but the lensflares and sun glow are colored, too. it's because only a small portion of the sun's light forms flares, glow and the blinding effect. The color of blinding must match the glow and flares.

It's a result of how human eye work.

There are two types of visual receptor cells in the retina: cones, which there are three sub-types with sensitivity tuned to red, green and blue photons respectively, and rods, which sense all visual wave lengths about equally.

Cones are responsible of our colour vision, but there are very few of them compared to rods. That means humans can only see colour well in good lighting, and when it goes darker, things become closer to shades of grey.

In addition, cones are concentrated on the "yellow spot", or the area of sharp vision in the middle of the retina, while rods are spread more evenly to provide peripheral vision that mostly detects movement. The actual field of sharp vision is actually very small, but the visual cortex does this neat "auto-complete" -trick that is based on fast involuntary movements of the eye, and saves the field of view to the visual cortex, giving an illusion of even overall sharpness in the field of view. You can test this by holding your eyes in fixed position consciously (this is hard and takes a lot of effort and concentration); after some time, your field of view will start fading from the edges as there are no updates for the visual cortex to keep up the illusion. Normally, any movement in peripheral vision triggers a reaction where you normally glance there, which updates the movement. It's actually not too different to modern video codecs in some ways. But I digress.

As a result of the structure of the eye, a very bright light of any wavelength would be interpreted as (painfully) bright light, overflow from the rod cells dismissing the colour information sent by the cones.

There are other reasons why the blinding effect in FS2 is grossly inaccurate and simplified, though, but I won't go there now. :p

OK, but that would only be the case if it's so bright that the entire screen whites out or at least one of the channels is clipped. But often the effect ingame is much weaker, with just a bit of brightening of the entire screen. Besides, I always thought that effect was meant to simulate the scattering of light in the human eye.

By the way: Human eyes don't produce any noticeable lensflares.

And spacecraft can't change course without side- and front-thrusters - so what? It looks cool, doesn't it? :p (the lenseflare of course)

Yes i know, I'm OK with the flare. I just had the thought it would look even cooler if the blinding effect would match it's color, while at the same time beeing realistic and not costing any additional performance. + beeing easy to implement.

Blinding not being OMFGWHITE could be cool.

Re: Color of sun blinding effect
How about the screen starting to be washed with the respective suns' color, then switching to white as it gets more intence?  You know, like how the upper end of the color selection, no matter what the color, is white in M$ Paint when you "define custom colors" and the low end is always black.

For example:

Blue, overloaded by white from glare:

Hue: 166
Sat: 240
Lum: 240
Red: 255
Green: 255
Blue 255

Blue, dark:

Hue: 166
Sat: 240
Lum: 80
Red: 26
Green: 0
Blue: 170

Blue, made black by lack of light:

Hue: 166
Sat: 240
Lum: 0
Red: 0
Green: 0
Blue: 0

Re: Color of sun blinding effect
The good thing with white effect is it doesn't look particularly stupid. Certain other colours probably would (possibly creating annoying surprises).

Re: Color of sun blinding effect
I say it should stay white. But (if any more work eventually gets put into post-processing) it could be a more sophisticated effect than what we've got now.

Re: Color of sun blinding effect
this may not be the appropriate place to put this, but everyone seems to prefer existing threads to new ones. 

can the blinding effect be turned down or off?  honestly it's about to make me punch my monitor.  there is a sun in EVERY mission, and as it turns out, many of them right behind/next to the objective, or whatever you end up facing for the majority of the mission.  it also doesn't seem to matter how far away the "sun" is, it ALWAYS completely blinds, even if it is seemingly pluto-distanced.  i find it rather irritating and occasionally physically painful.
I like to stare at the sun.

being able to scale the intensity and cone of effect from fred would be useful to simulate distance.  I would also like see an option to be able to turn the effect down from a players perspective even if it just enough to take the painful edge off a total white out.

Re: Color of sun blinding effect
I, for one, desperately want to see sun blindness have a maximum upper limit (based on looking directly at a single sun in retail) and have scaling down based on sun size. This way if you're simulating the orbit of, say, Neptune, you aren't blinded by a star that's only slightly bigger than the ones in the background; and when there's multiple suns in the field of view (as in most MediaVPs missions), you aren't totally blinded.

Re: Color of sun blinding effect
so this can't be currently done using the lighting tags or whatever currently? i REALLY want to not be blinded any longer.  at this point i'd rather have it not glare at all than blind me.

You can always overwrite any existing stars.tbl and add $NoGlare: to the end of each star entry. It'll get rid of the glare completely.
