Hi,
Cell phone scene, I receive material in dpx log, I apply the cell phone, at the end I use a color node to see if it is creating a halo before exporting the applied material and a matte, when this material arrives at the colorist, it seems that it presses so much contrast and color that the matte seems to not hold and ends up creating a halo, I solve this problem by sending the cell phone applied without the fingers to the colorist, and a cell phone with the fingers to the colorist, import this in Flame, and with Paint I reveal material with color without the fingers to remove the halo, but this flow of many cell phones ends up being insane.
Sadly there no workarounds for a dumb colourist.

I don’t think I’m understanding correctly. Is the colorist in essence doing the comp? Or are you sending the comped cell phone with a matte that has the screen as white and everything else (including the fingers as black?) I’ve had problems with colorists before where they don’t understand that the mathematics of how I’m compositing a monitor insert or a Bg for a blue screen shot mean that pushing something way brighter or way darker than what I submitted as the comp will break the edges and cause either halos or dark lines. If they’re pushing it too hard they need to tell you that they want it darker or lighter and you can adjust your comp. Mattes in color should be used for minor adjustments in hues and small adjustments in luma, not basically a means of recompositing. That being said, You could see if the colorist can provide you with a lut as well that you can check your comps with before sending. Finally, you might convert from log to acescg to do the comps and then back to log for the colorist. I’ll agree with @cnoellert above though and say sometimes this can be a, how should I put it, frustrating battle…
My cell phone is in chroma green, I’ve already darkened the maximum green I could, because the cell phone art comes in linar, I use color manager to convert lin to log, the problem is that I can’t change the color of the cell phone art to compose, I have someone to send the composition kind of cool, just applied the art on the cell phone together with matte, but the colorist complains that there is too much halo coming, my composition is to blame.
Try doing the whole comp in ACEs? So converting the plate from log (whichever kind of log you’re in, ie LogC to ACEScg) and the insert from sRGB or Rec709 to ACEScg and comping everything in linear. You can still key in log if you’d prefer just piping your keyer from the plate pre-converting to ACEs. I would also try an additive key on this (I just use it as the fill, not the comp). Can you share anything privately? Maybe I could take a look? If a screens super bright and they want a dark insert there’s always going to be pain there, BTW

Yup. Over-bright screens are a special hell.
