It's all about fame, and there's no business like show business!
So what about creating a colourspace bearing your name?

That's what Joseph Holmes does for his (wonderful) landscape pictures:

Some custom design working colourspaces will make your tools behave a certain way that might be more desirable.

Closer to our industry, the guys at Colorfront have set in OSD/Transkoder a base "Colorfront" look based on the experience they have collected working with the best colourists and colour scientists in the world.

And then obviously you connect that back to ACES so everybody can see your awesomeness in a standard way

Hi Cedric.

In context of ACES.

So If I chose DCAM 4 or 5 as my working colour space I would have a lot more gamut to work with than for instance P3. Does this translate to more colour information in the final rendered material once going through VFX for instance? Having more gamut in my working space should allow for better final Grade and matching with ACES media that has been unprocessed by a VFX station right? DCAM 5 covers the entire of the CIE 2 degree Chromaticity Diagram which is close to ACES Gamut.

Between D.I and VFX, and we need an ODT that is a DCAM 5 compliant Transform for ACES.

Are all the render engines for 3D and compositing able to use all this extra floating point data? I assume we would have an IDT Transform from DCAM 5 back into ACES to use the wide gammut renders in the D.I Suite again?

it's not so much about having more colours than really having more info where you need it for your tools to behave properly.
Maths to convert colours between defined colourspaces are pretty straight forward, basically combinations of gamma type transfer functions and 3x3 matrices.
ACES itself brings you all the colours you need. As long as you use ACES for input and output, as a transport/connecting space, you keep all data. Just need to make sure that your creative system can keep the negative values if you're using a narrower working colourspace.
