Color space/mode

[hrvojezg00]

We are struggling a bit between our and our client monitors, so we are not sure if they see the same colors, etc. What is the best way to go, srgb/Adobe RGB or something else? We just bought an Asus PA32UCXR, which is set to Native mode by default, but we aren˙t sure what color space that is. Any advice/setup would be greatly appreciated!

"Native" is just random wide-gamut, so lot's of colors, but not any specific space.

When Corona implements full support for 3dsMax 2025 OCIO, you can set your monitor to anything, though ideally AdobeRGB or DCI-P3 for wide-gamut workflow. It's still best to export in sRGB unless your clients know what color-managed pipeline is, or they're on Apple device.
Right now, your best choice is to either set sRGB mode through monitor OSD menu, or through this free utility in desktop https://github.com/ledoge/novideo_srgb

Hi Juraj, sorry for the late answer. I had no idea you had answered. We ended up using AdobeRGB and sending clients in both AdobeRGB and sRGB. It`s far from ideal, but it works for now. Unfortunately, there`s not much talk about this thing on the forum, but it`s crucial in our business.

It should be fully supported, besides the DCI-P3 and Rec.2020 rendering color spaces (there is ACEScg of course).
Is there something specific which is not working for you?

[Juraj]

I don't mean just internal rendering-space or respecting input. Is there anything output wise? Any check-box in Framebuffer? Does Corona saves the file with embedded color-profiles?
I didn't see any announcement, so this would be good news to me.

And DCI-P3 (and custom ICC) would be the useful one for design/graphic industry.

Can you link me to where it states what is supported?

Corona does not embed color profile information, unfortunately, I am not even sure if with 3ds max save dialog (Corona uses it under the hood) it is possible.

For 3ds Max color management - everything should be supported by Corona, unless there is a warning message about it (e.g. specific rendering color space).

If everything is supported than maybe you would be interested in this:

it is meant to replace your default ocio config from Max. just expanding on the defaults so this will not break any scenes (unless you are on exotic hdr display, I removed those for now as this config is based more on what you can find in Maya - different display list)

I will add an option to load your ICC into max via ocio config soon.

Im just reading a few threads on this topic at the moment trying to ascertain how to get consistent sRGB or AdobeRGB outputs from Corona now that colour management is a thing.
This seems to be the most recent thread discussing it and sorry to hijack it for a slightly different question. But If someone who has a better understanding than I could post some advice on what settings to use within colour management and then what to do within photoshop to ensure consistency between the VFB and the image im seeing in photoshop that would be great.

Juraj, i followed some steps from a post you made a few years ago which were very helpful thank you. But now colour management exists in max is there a better way to ensure consistency? Or does the missing profile assignment in the max save system still dictate that the below is the best way?

This is the comment i mentioned above.

This is correct workflow for this monitor for 3dsMax/Corona.

1) Monitor OSD Menu: Select sRGB mode. Then adjust brightness to your liking. (Fun fact: Calibration is also done to exact brightness levels, but if you move it +/- 50perc. the difference in accuracy is not drastic).
2) Type Color management into taskbar in Windows, select your monitor, check "Use my settings" and select "sRGB" ICC profile. Set "Use as default".
3) When loading any rendering into Photoshop, you don't need to do anything if your settings are set to "Don't Ask". It will stay unmanaged and you only need to "Assign" sRGB profile at the end of export, for examply when saving to final file. Don't convert to any other profile.

The above workflow doesn't work for high-gamut displaying (DCI-P3, HDR workflow,etc..) or printing (AdobeRGB, LAB,etc.). But since 3dsMax & Corona are not color managed (Autodesk Maya and Vray for example are), this is the best scenario to use right now. Least headaches. Colors are always correct, you're just not using wide-gamut capability, which is ok since most devices are sRGB only, even today.

adobeRGB display is in the default OCIO config.

I didn't update to 3dsMax with OCIO yet. I am also confused by some of the answers Corona Team gave in relationship to Corona synergy with that OCIO config (they never gave exact answer and my feeling is the answers are almost always partially incorrect).
Until then, can't really answer much.

Nothing to stress about. OCIO main role is in VFX production (compositing). Where there's non-standard (un-Linear workflow - many different Camera Inputs & specific Display Outputs, with diverse artists/studio sets in between). Using it, user basically 'describes how elements/components talk to each other' with intention to keep (digital) 'Colour' consistency throughout whole pipeline/framework, making production more effective and cheaper.

Simply keep your LWF, know your white point value, let compositors master their stuff. And in this regard, best you can do is to provide/supply clean HDRIs. Unless requested otherwise, off course.

TL;DR
It's alike taking care of how HDRI color is mapped to 8bpc displays (sRGB) and/or prints, but in cinema/film industry

 
BTW:

Since "color space" identifies a particular combination of the color model and the mapping function, the word is often used informally to identify a color model. However, even though identifying a color space automatically identifies the associated color model, this usage is incorrect in a strict sense. For example, although several specific color spaces are based on the RGB color model, there is no such thing as the singular RGB color space.
