Image Trace has the ability to limit color when tracing. I'm looking to do something similar, but with artwork that is already vector. I also knw that I can use the Edit Colors function, but that requires a manual ressaignment. I created an Object Mosaic and there are at least a hunderd or two hundred different shades used. I am looking for a way to limit the colors without having to drag and rearrange them all manually in the Edit Colors dialog box.
I also know there is a way to choose a color group when using the Edit Colors function, but it doesn't apply to colors correctly and sometimes really misses the mark. What would be really cool if there was a way to limit the colors as part of the Object Mosaic function.
Afterwards you might still need to use either the "Combine swatches" function or "Edit colors" to make them exactly the same color. That might or might not be more tedious than using just "Edit colors" which you initially excluded.
I think I finally figured it out. There are two colors groups available by default in the Recolor dialog box (Grays and rights). They each have 6 swatches. In the "Colors" dropdown, the choices are 1, 2, 3, 4, 5, and All. So it would seem that you're limited to 6 colors when reducing colors. But that's not the case.
Did you manually create the colors for Color Group 1 or did it choose one from the current colors panel next to each color? I am trying to reduce the number of colors in a watercolor turned vector piece of art.
Summon Phantasm Support is a support gem; it does not summon phantasms, the skill it supports does. If that skill has any minion bonuses, naturally or from other support gems, those bonuses can also apply to phantasms. For example:
Note: Summon Phantasm Support is an old support that predates hybrid gems. Its coding is acknowledged as problematic[4] and the above interactions may not be functional. Ingame confirmation is recommended.
This cycle of excitement and letdown with my thiol chasing trials is part of the reason I was so interested in the work done by Omega Yeast and Berkeley Yeast this year in engineering yeast strains designed precisely for biotransformation. Using CRISPR technology (at least with Omega), they are now able to create hazy IPA yeast strains that, like many of the wine strains studied prior, have the necessary gene (IRC7) to produce the required enzyme (beta-lyase) during fermentation to unlock thiols.
Rather than getting into a lot of technical text (most of which was covered in a previous post on bioengineered yeast strains), below is a flow chart of sorts that helps explain how and why their power in unlocking bound thiol potential in hops.

Because many of the free thiols from the Sauvignon Blanc grapes were released into the wine, the skins are still valuable because of the incredible number of thiol precursors, mainly the cys-3MH thiol precursor. Most bound thiol precursors in hops and wine grapes are glutathione-thiol (glut-thiol) and not cysteine-thiol (cys-thiol) conjugates. Bioegineered yeast strains can liberate bound cys-3MH precursors, which is why most of the research focuses on this class. However, hops and wine contain loads of glut-3MH precursors as well, and this post will get into how the potential of introducing glut-3MH precursors into the mash might help free even more 3MH.
Phantasm is a project that Jos has been working on for over three years. Living in New Zealand, which is known for its ultra tropical passion-fruit-like Sauvignon Blanc wines, Jos thought there might be potential for incorporating these thiol-rich wine grapes into beer. After all, one of the main thiols in these wines (3MH) is also key thiol brewers seek in hops.
This focus on using only high thiol blocks of grapes from winemakers is becoming increasingly crucial to the Phantasm process; the newest crop (2021) will include a known high thiol block, for example. To enhance the thiol potential even beyond terroir, Phantasm is improving its processing methods to concentrate the thiol and thiol precursors even more, potentially making a 3 g/L dose equivalent to an 8 g/L dose.
Along with other reasons, you may want to consider dry-hopping cool. This might help limit metal extraction from hops into your beer and potentially less thiol stripping (again, this theory would need to be tested).
Looking at our Locksmith recipe and going with the theory that hops may be pulling out thiols, we chose to go with a low dry-hop charge in the collaboration of only 22 pounds (in a 10 bbl batch) of Mosaic Cryo Hops (usually we would dry-hop with 2x this amount in a DIPA). The logic is that a smaller charge could help reduce thiol losses, and Cryo, with less vegetal material (and likely fewer metal concentrations), might strip fewer released 3MH thiols. Lastly, choosing to dry-hop post-fermentation might also help prevent a loss of thiols as the Omega test saw much higher concentrations with the day 7 dry-hop vs. the early active fermentation charge.
As mentioned at the start of this post, we wanted to take the collaboration of The Locksmith a step further in terms of analyzing the beer by sending samples to a lab called Nyseos in France to get tested for thiols (3MH, 3S4MP, and 4MMP). We were instructed to dose our sample cups with metabisulfite to help protect the thiols during transit. After adding the metabisulfite, we then froze the samples and shipped them to be analyzed via LC (not GC). Thiols, because of their low concentrations, are hard to test for and only a handful of labs even offer the service. The Nyseos lab uses very robust and controlled processes that allow them to quantify thiols accurately.
Again, leaning on the knowledge and experience of Laura Burns at Omega, it was interesting to hear that in multiple samples they sent to Nyseos to get tested for thiols, those that were not treated with metabisulfite came back with samples all over the place. The frustrating results were likely the result of any oxygen ingress absorbing the thiols.
Although additional research should be done in this area, it seems plausible that because thiols are so susceptible to oxygen, they may also be acting as one of the first waves of defense against oxygen (similar to sulfites). This can potentially mean that when using products like Phantasm and bioengineered yeast strains designed to free thiol precursors, you could be extending the hop-forward shelf-life in your beer. Because the thiol concentrations can be as high as +1,000 ppt (for free 3MH), even with some oxygen ingress and eventual thiol absorption, you could still be above the 3MH threshold and the total thiols taking the oxygen hit, not other important hop-forward compounds like free monoterpene alcohols or the eventual malt staling aldehydes (post-fermentation hop oils might also help reduce staling aldehydes).
Interestingly, you can see from the chart pasted below, when lager beer was spiked with cys-3MH precursors, there was a conversion of the bound 3MH (cys-3MH) to free 3MH with time in the bottle. Although the conversion was relatively small (ranging from 0-19% conversion across the tests), you can see how increasing the thiol precursors in the beer could benefit its flavor longevity, especially when using a yeast strain designed to free those thiols. So, free thiols are likely to oxidize post-packaging (to a lesser extent if using metabisulfites), but thiol precursors can also continue to be released into a free state during aging.
So, to sum up, the oxygen aspect of heavy thiol beers, it seems plausible that ignoring the sensory part altogether, high free thiol producing beers may act as the second wave of oxidation protection after the sulfites have been used up. Essentially, brewing high thiol beers, avoiding oxygen during dry-hopping and packaging, and even considering adding small amounts of metabisulfite at dry-hopping could all be ways of extending the fresh hop-forward shelf-life in IPAs.
When researching the book, The New IPA, it was interesting to learn that even protein-derived thiols from malts may serve a protective role in hazy beers, similar to how free thiols like 3MH might. Essentially, sulfites are the primary antioxidant in beer (produced naturally during fermentation or added post-fermentation via metabisulfite), and these protein-derived thiols and free hop thiols can act as a secondary antioxidant to encourage redox stability (oxidation).
So, to increase the protein-derived thiols to help with stability, we should be using grains high in the LTP1 protein. One possible way to do this is by brewing with a high percentage of under-modified grains (big fan of chit malt). 4
To speculate even further, I wonder too if malted grains that are under-modified (like chit malt) might be higher in the LTP1 protein (leading to potential higher shelf-life) and one of the higher cys-3MH precursor grains which a bioengineered strain can then act on and free. At least for The Locksmith beer, we brewed for this post (which included chit malt), it was one of the highest thiol beers tasted to date compared to various other beers Omega has tested.
Laurent Dagan continues to research malt and thiol precursors, and I look forward to reading his results. So far, they have done experiments testing 15 different malts, and the barley malts were all higher than non-barley (rice, sorghum, and wheat). As you can see from the chart presented in an online presentation from Dagan below, not all barley malts are equal precursor potential. It seems that less a grain lightly kilned malts help to retain these precursors.
