The color is fine but there should be a least some bloom if the "camera" is over-exposed. All the detail in the taillights.. should be blurred or obscured if the color is distorted so far. That's what stands out to me.

The ambient-light taillight color shift effect is a good idea, but it needs refinement and consistency across conditions (strongest at night, absent in bright daylight). Right now it's just immersion-breaking--"who replaced my brake lights with turn signals?"

Red LEDs should never appear yellow--they don't produce any other wavelengths than visible red. Overexposure turns them pink, eventually white. White LEDs filtered to red could overexpose to yellow. AFAIK reds are cheaper to make, and brighter than filtered whites, so most LED tails have red diodes.

FH4 has the opposite problem. Too many tails over-expose to white/pink, instead of orange, like they should. They never wash out though. If they turn white it's only in the brightest area and accompanied by bloom. Overall, it feels natural. I haven't touched FM7 or PCars 2 in a while.

LEDs, pink/white overexposure.






These should have more orange-y lights.





Only car I could find with properly orange over-exposure due to white incandescent bulbs.

Edit: I've found pictures of incandescent taillights with pink over-exposure. Most are orange/yellow.. but by that point there is strong blooming too, occluding the detail and blurring the shape of the lens/cluster. To reasonably shift the color of tails all the way to yellow, or white, overwhelming bloom should be present as well...

I use an LG 25UM58-P. It's a 25-inch, 1080p 21:9. It's like a 27-inch 1440p with 360 vertical pixels removed.

Thanks for this thread, because it's all I kept thinking about while watching today's ForzaRC Invitational! 😂

I am using an HDR enabled LG OLED TV and I have it setup to use HDR in Forza Motorsport 7 and I still am able to see the those "orange" break lights. I think it's less of a problem with the HDR implementation and more of a design choice by the developers.

To be honest I would not have noticed this without people talking about it here and actually it doesn't change my enjoyment of the game. I stumbled upon this topic while trying to figure out why each tunnel is so dark in this game, since the car headlights cast no light on those tracks, but I could improve the issue by raising the brightness in the main menu options.

The brake lights look perfectly okay to me in FM5 and 6. It doesn't change my enjoyment of the game either - but makes me wonder why it's even an issue to begin with, since they were so heavily advertising 4K/HDR/60 fps from the get-go. I might have been okay with it if it were an issue in older FM games - but it's never been one, so why now?

Like I mentioned I believe it is a design choice. My guess is that the art directors wanted to sell an artistically more gloomy and more dramatic looking game, maybe even so the HDR contrast is more eye-popping when you have bright light sources in dark images. The rain sections certainly look way more darker in FM 7 than in FM 6, here is a nice comparison video showing the difference between FM 6 & FM 7 in rain:

Another theory I have since those tail lights are now more visible during low-light races (in FM6 you can barely tell if the tail light is on or not) the developers/designers maybe decided to use orange break lights so the player can tell if cars in front are actually breaking or not.

Also found a nice video showing off the orange tail lights during a night race:

I did not bring up PCARS 2 because this isn't really the forum for it. Do you see weird colors on the brake lights on your HDR screen while playing PCARS2?

I swear none of this nonsense was around before they decided to market "HDR" in games - although most games still do a standout job or reproducing great colors, including accurate reds: GOW 4 and 5, SoTR, Witcher 3, and many others. Don't know why this is now an issue in some racing games. Ironically, it was never an issue in FH2, FM5 or 6 - this is before they started implementing HDR.

I still can't get over what a strange design choice this is - do they want the brake lights to look cartoony when they light up?

I've only played the demo of Project CARS 2 back in 2017 when the game came out, but I don't remember how the break lights looked like. I didn't really pay attention to the color of the tail lights back then. I've bought Project CARS 2 during a sale for Xbox One, but I haven't started playing it yet. Plus I read online some people saying that the PCARS2's HDR implementation isn't that good.

I'm not sure if this has something to do with HDR. The first Project CARS did not support HDR and in that game the Corvette C7R looks like this:

One comparison video between Project CARS and Assetto Corsa Competizione shows that Assetto Corsa has red lights.

I've check online and some people actually have orange tail lights installed in their cars in real life.

That's what I've been trying to say all-along. In any view aside from the first person views, the game has camera artefact effects, as it should because it's through a camera. You can see lens flair, dirt and particles on the lens itself and probably over-exposure of the tail lights which most cameras do.

** Fair enough - but I would have preferred to see colors in the game, especially tail lights, the way the human eye sees them, as opposed to a camera lens. Camera lens do overexpose tail light color and makes them appear pink, orange, yellow - all kinds of funny shades. No stranger to that.

Yes Forza does need to tweak its lighting model slightly, though the game still looks good enough imo. There needs to be more of a sparkle effect instead of a bloom and glow effect on paint in particular and on lights and there needs to be a general reduction in bloom and exposure but these are small tweaks.

** Oh I never knocked on the game once - I love the 'dramatic' look of the game, makes it very immersive and enjoyable to play. I do agree that the paint sparkle effect has taken a hit; it was far more convincing in FM6 and 5. The bloom can be over the top during the day, but ironically, the headlights and tail lights never appear to have the right level of bloom and glow at night - in fact, they look brighter during the day. Odd design choice - or perhaps an after effect of the compromises they made to keep the action at 60fps locked. I still wish they had spent more time tweaking the bloom and exposure for both day and night. Again, it looks really good in FM6, at least to my naked eye.

Comparing Forza Motorsport 5 and 6 to 7 isn't fair. They're all pre-rendered, pre-baked, not dynmaic weather systems or no weather systems at all. Of course they're going to look better on current hardware. When you introduce weather systems and effects such as dynamic reflections, shadows, lighting, saturation, contrast, skybox, sun, clouds, rain and so on so forth, something needs to take a hit and unfortunately that's slight hits to graphical fidelity.

** Fair enough - no further comment! :)

Now on the next hardware, there's one of two scenarios:

1. The game will become even more dynamic with probably a 24 hour day to night and back to day cycle, with more weather types, effects and more conditions in general with minor improvements to graphical fidelity.

2. The game stays with its current level of dynamic options but the graphics improve considerably.

Personally, I would prefer option one and with how the franchise has progressed since Forza Motorsport 5, that's probably the option they'll choose and I personally think it's the correct option because the graphics are good enough already and aren't as important as content, features or physics.

** I wouldn't mind either option TBH, although opt. one seems sweeter! I would, however, want them to focus much, much more on car sound character and nuanced physics modeling for each car. It's going to be tough - sure - but is it impossible? Not by any means, not with their budget.
